Dna Transcription, Translation Quiz Study Guide Essays

Dna Transcription, Translation Quiz Study Guide Essays Dna Transcription, Translation Quiz Study Guide Paper Dna Transcription, Translation Quiz Study Guide Paper Study Guide 3/1/11 1. Describe the three parts of a nucleotide and how they bond to form a nucleotide. The three parts of a necleotide are a carbon sugar, a phosphate group and a nitrogenous base. The carbon sugars bond to the phosphate groups by covalent bonds while the nitrogenous base bonds with it’s compliment by hydrogen bonds. 2. Summarize the role of covalent bonds and hydrogen bonds in the structure of DNA. The role of covalent and hydrogen are as follows. ydrogen bonds, being easy to break, allow the DNA to break so that copies can be made. Whereas covalent bonds keep the sugar and phosphate together, which allows proper placement and structure. 3. Relate the role of the base pairing rules to the structure of DNA. The bases in a strand of DNA relate to the base pairing rule due to the combination of GC and AT, make equal strand, that is held together by a hydrogen base. 4. What is the primary function of DNA? What is DNA long chains of? The pri mary function of DNA is to code for information. DNA consists of long chains of amino acids. 5. State the names of the nitrogenous bases using purines and pyrimidines . The bases in a strand of DNA relate to the base pairing rule due to the combination of GC and AT, make equal strand, that is held together by a hydrogen base. 6. Explain Chargaff’s rule of base-pairing. Chargaff observed that the percentage of adenine equals the percentage of thymine, and the percentage of cytosine equals that if guanine in the DNA of a variety of organisms. So being opposites, they attract. A to T and C to G. 7. Show how dehydration synthesis (condensation reaction) bonds occur at 2,3 and 5 prime carbons of sugar. Monomers join together to form polymers by removing water to form covalent bonds. It takes OH from sugar on the 5th carbon and takes H from phosphate group to kick off water and form covalent bond. 8. Explain how the DNA double helix is formed using 3’-5’ linkages, anti-parallel strands, complementary base pairing and hydrogen bonds. As the DNA strands separate, free nucleotide monomers from hydrogen bonds with the exposed nitrogenous bases by the process of complementary base pairing. Also one side called the leading strand when reproducing goes from 3’ to 5’, but the lagging strand due to anti parallel strands has to go from 5’-3’ this is another factor in the double helix. 9. Understand the importance of the enzymes responsible for DNA replication. The role of helicases , and the role of poylmerases are as follows: polymerases add complementary nucleotides to each of the original strand of DNA, as well as replicating, and reparing. Helicases, on the other hand, separate the DNA strands, breaking the hydogen bonds between the complementary nitrogenous bases. 0. When and where does the process occur? What is the significance of DNA replication? In the nucleus for the purpose of repairing the body. 11. Explain semi-conservative replication and how it related to our outside simulation. DNA is a semi-conservative process because it uses half of the original DNA strand, and a new, freshly replicated stand. 12. Explain transcription. creatin g a complementary RNA copy of a sequence of DNA 13. Where does it occur? What is involved in the process? Transcription occurs in a the cells nucleus. 14. Given a genetic code- be able to find amino acids based on the chart. Will do 🙂 15. Given a DNA strand, be able to find complementary strand, the mRNA to it, and the tRNA to the mRNA. Will do as well 🙂 16. During translation- what components must be aligned for the process to happen? Where does this occur? Why? Each of the 20 amino acids must be aligned with their corresponding codons. It occurs in the ribosome just as the strand is being ready to replicate to allow the correct amino acid to attach and align with the correct codon. 17. What are the different types of RNA? Messenger RNA, Ribosomal RNA, and Transer RNA. 18. What are the differences between DNA and RNA? In DNA the A matches with a T and a G matches with a C, but in RNA goes from A to a U and G to C. Also RNA is in short one sided strands and DNA is in a double sided double helix long strand. 19. How is DNA changed into RNA? Why is it important for this process to occur? RNA Helicase attaches to the promoter and seperates the DNA in one section. Then the polymarase RNA comes and matches up with the DNA (AU)( GC). 0. How is DNA related to how proteins are made? Proteins are created from the messages the DNA send out in the form of RNA. Then the RNA is turned into a protein using amino acid chain that is made in the ribosome. 21. Explain what enzymes are significant to transcription. RNA polymerase and also DNA polymerase 22. Explain the process of translation. In translation, messenger RNA produced by transcription is decoded by the ribosome to produce a specific amino acid chain, or polypeptide, that will later fold into an active protein

Whats Actually Tested on the ACT Science Section Skills and Topics

What's Actually Tested on the ACT Science Section Skills and Topics SAT / ACT Prep Online Guides and Tips Are you studying for the ACT? Not sure what to expect from the science section? You might be surprised to know that the science section one of the most commonly misunderstood parts of the ACT. So what exactly is tested on the ACT science section? And how much science do you need to know to do well? We'll break down this section for you with example questions so you know exactly what to expect. ACT Science Section Format The ACT science section is 35 minutes long and contains 40 questions. That means that you have about 53 seconds to spend on each question. The science section’s format is more like the reading section than the math section – which is surprising for some students! Each question on the math section has its own task or problem. But for both the ACT Reading and ACT Science, you have to read a passage and then answer a series of questions about it. There are seven passages on the science section. Each passage could contain graphs, charts, experiment summaries, or conflicting viewpoints from scientists. Every passage is followed by four to seven questions about it. So to do well on this section, you need to be able to quickly but accurately read and understand scientific data. What Does AP Science Test You On? Although the ACT Science section includes a wide range of science content, it tests your scientific skills more than your knowledge. As the ACT puts it, â€Å"the Science Test †¦ measures the interpretation, analysis, evaluation, reasoning, and problem-solving skills required in the natural sciences.† In other words, the science section tests skills, not specific facts or topics. So how exactly do you learn these science skills? From taking science classes in high school. The ACT website recommends you take at least three years of science in high school, and have taken at least one biology course and one physical or earth science course by the time you take the test. Aside from being more fun than the average class, doing science experiments helps you prepare for the ACT! By taking science courses, you’ll learn about the scientific method, how to collect and analyze data, and how to evaluate a theory or hypothesis. These skills will help you succeed on ACT Science. By taking biology and earth science, you'll get enough background on science terminology to be able to process ACT Science topics. Content you're tested on could include biology, chemistry, physics, and earth/space sciences (including geology, astronomy, and meteorology). As an example, the Preparing for the ACT official practice test science section includes passages about finch beak depth, the process of ions being precipitated from the earth’s atmosphere, cloud cover, acid-base titration, stellar evolution (how stars evolve), and the human threshold of hearing. However, the ACT does not expect students to be experts on such a wide variety of science topics. Using these kinds of topics as starting points, the science section will ask questions about data representation, the research process, and conflicting hypotheses. So if your scientific reasoning skills are strong, you will be able to answer any ACT Science question – even if it’s about an obscure topic like finch beak depth! That said, science background from biology, earth sciences, and chemistry will be helpful, because you won’t be intimidated by scientific terminology on the test. As an example, it will be easier to break down a passage about finch beak depth if you are familiar with the concept of natural selection. But remember you don’t actually need an advanced knowledge of particular science concepts to do well on this section – you just need to be able to read and interpret graphs and studies. Now let’s explore the exact question types you will see on ACT science. ACT Science Question Types There are three different question types you will see on ACT science. The majority of questions focus on having you break down data and experiments, though you will also have to compare conflicting viewpoints between scientists. Check out the three different question types below to learn more. #1: Data Representation (30-40% of Questions) These questions have you read graphs, interpret scatterplots, and explain information presented in tables. While some knowledge of the subject being tested is helpful, what is more important is your ability to read and understand data. As an example, check out this question from an ACT practice test: Source: ACT Assessment Practice Multiple Choice Test, 2004. The topic of this passage is metamorphic rock formation. However, you don't need to be an expert on that, or even know much about metamorphic rocks at all, to break down the chart. The question asks you which conditions a Facies G rock is most likely to form under. Looking at the area of the chart representing Facies G rocks, you can see they form with pressure between roughly 10 and 14 kb, and temperatures between 200 and 1,000 degrees Celsius. Looking at the answer choices, only one (choice J) lists a pressure reading that a Facies G rock could form under. Therefore J is the correct answer. In other words, the question is testing your ability to read and interpret the graph. The question is not testing your knowledge of metamorphic rocks. #2: Research Summaries (45-55% of Questions) These questions require you to interpret the design and results of experiments. Again, specific content knowledge isn't as important as knowledge of the scientific method and data collection. Check out this example question to see what we mean. The topic of this passage is elaiosomes, nutritious structures in seeds that attract ants. However, you don't need to know much about ants, seeds, or elaiosomes to break down this study and know which variable was controlled. A controlled variable is a variable that remains constant. So all you're looking for is the variable in the experiment that was kept the same. Reading the study description, we see that "Two seed dishes were placed in each site." This makes G the correct answer. (The other answer choices, number of ants, mass of elaiosome of each seed, and type of seed taken by the ants, were not described as constant in the study summary.) So to get this question right, you have to know what a controlled variable is and how it relates to scientific study structure. You do not have to be an expert on ants or seed germination. This is why taking science classes and becoming knowledgeable in the scientific method is so important to doing well on ACT science. #3: Conflicting Viewpoints (15-20% of Questions) The final question type on the ACT science section tests your ability to understand, analyze, and compare alternate viewpoints or hypotheses. These questions will center around a single situation or problem, and you will read two different viewpoints and compare the similarities and differences. Check out the example below. The question is asking you to figure out the main point of disagreement between the two scientists. In this case, the disagreement becomes clear in the first sentence of each opinion. Scientist 1 says "the object was a comet," while Scientist 2 says "the object was a stony asteroid." This makes answer choice J ("the type of object that entered Earth's atmosphere") the correct choice. The scientists do not disagree on the other three answer choices. The location of the event (choice F) and speed of the object (choice G) are given in the initial description, and the scientists don't disagree on the density of Earth's atmosphere (choice H). Once again, your familiarity with the content, in this case comets and asteroids, is not important. What is important is your ability to read two different points of view and quickly hone in on similarities and differences. Even if you knew nothing about comets or asteroids, it would be possible to get this question right by using critical reading skills. Here's a summary chart of the types of questions you'll see on ACT Science: Type of Question Skills Needed Number of Questions (Percent of Questions) Data Representation Read and understand data About 15 questions (35%) Research Summaries Interpret the design and results of experiments About 18 questions (50%) Conflicting Viewpoints Compare, contrast, and analyze opposing viewpoints About 7 questions (15%) Bottom Line If you can read and interpret graphs, charts, and tables, analyze differing opinions, and understand the scientific method and study design, you will do well on ACT Science. This section tests your scientific skills, not your knowledge of scientific facts. As you practice for this section, focus on how well you are able to quickly read and understand data and experiments. Also make sure you are able to compare different viewpoints and find similarities and differences. Doing specific ACT preparation and using practice questions will help you see if your scientific reasoning skills are strong enough to do well on this section. What’s Next?

Performance management in action Essay Example | Topics and Well Written Essays - 2500 words

Performance management in action - Essay Example Nampak plastics are a South African owned company which is a strong performer in its industry and is strategically located to supply the entire United Kingdom. It has eight manufacturing sites from Glasgow to Gloucestershire. It was noticed that the morale was very low in organisation and people were also treated badly. Few employees were seen running around the organisation to do everything and the rest employees were seen to sit around watching. The culture of the organisation affected its customers. In fact, Nampak was found as the worst supplier to its customers. Customer’s complaints were also reaching at large numbers. So, it was decided by the organisation to develop a legacy on the engagement and involvement of employees from the bottom of organisation to up. Eric Collins, the managing director of Nampak Plastics, conducted a meaningful survey of employee satisfaction in the company. In the feedback, it was found that around 80 percent of staggering employees do not pr efer Nampak as a place to work with family and friends as they thought that everything was wrong. To make its improvement, certain key initiatives were taken. Initially, Collins took the attempt to meet with customers to hear what is going well in the organisation and what is going badly. In a session with employees, an incredible dissatisfaction was seen from the shop floor. Large number of blames was levelled towards Eric. Later on, Wright-Smith was appointed as the head of HR. The first action taken by her was the ban of word â€Å"engagement†.â€Å"engagement† as she opined that people could not be engaged by telling them to be engaged. Rather, the need of the hour is to run focus groups by asking people at various levels of organisation and at each site regarding what could make Nampak a better working place. However, the feedback raised was not so good and it gave rise to the three key themes. The first issue was poor communication about the business as people co uld not understand what was going on and they did not feel involved. Secondly, the training and development was poor as the employees could not feel that they hold a career there and had any opportunities of development. Lastly, they did not get any feedback on their performance as their managers did not make any communication with them. Focus on front line managers It was decide to implement a system of company-wide performance management. It was asked to the group of employees regarding what they wanted. They answered that they wanted not just objectives but personal development. So, the company provided training to all the managers, focussing that it is the quality of conversation that counts a lot, not just a proper filling of form.

Restructuring in business portfolio or its financing Essay

Restructuring in business portfolio or its financing - Essay Example This company has more than 70 establishments in more than 150 countries worldwide. (gsk.com, 2009) The restructuring of the company’s portfolio or capital structure can be attributed to the strategic priorities it seeks to undertake. As of 2008, the CEO of this company, Andrew Witty, stated that the GlaxoSmithKline Company had three main strategic priorities. The aim of these was to achieve sturdy growth rates, reduce the level of risk as well as improve the performance (financially) in the long-term operations of the business. According to the CEO, the industry of pharmaceuticals is set to encounter big challenges since there will be an unpredicted number that will lose their patent protection. This, thus, will call for the company to work even harder to fulfill the client demand for brand new types of medicines and those which are better to use. As he states it, the loss of patenting will lead to a number of payers wanting an apt cost-effective kind of healthcare. This pharmaceutical company is therefore setting out to improve the consumers and patients’ lives, which is in line with the shareholders’ requirements. He did not go without noting that the industry is faced with a lot of risk and a lower rate of growth to counter the same. Therefore, the companies in context need to seek greater levels of return from their R&D investments. Unique to the expansion of the GlaxoSmithKline Company is its balanced healthcare business-group as well as an overall lesser profile of risks. The aim is, thus, to ensure a better level of discipline in the provision of capital components across the various areas of the company’s businesses. This company has a future goal of generating sales revenue growth by way of supplementing strength focused on the main small-molecule business of pharmaceuticals. This will also be through new investments in the vaccines area, which is considered to be fast growing, and also the
