Many scientists originally believed that proteins were the carriers of genetic information because proteins were macromolecules with great heterogeneity and functional specificity.
15. Explain why many scientist originally believed that proteins were the carriers of the genetic information?
How would you prove that DNA is the storage molecule for genetic information? Why not proteins?
1. How would a scientist would recognize genetic drift, from a current population. Explain. 2. What factors would prevent genetic drift, and explain why (Good description of factors)
In general terms, explain why a scientist would use the chi-square test as part of his or her data analysis. What important information does it provide?
2. Explain how and why this form of genetic change occurs to influenza within a host. (Hint: is it due to reassortment between two Influenza viruses OR mutations?). Please be thorough in your response. You may draw it out if it helps. (2pts) 3. Recently, flu vaccines for 2017-2018 included protection against H3N2. What does H3 and N2 represent? Please spell them out for full credit AND explain why 3 and 2 stands for. You may need to refer back...
1. Why do fats provide more energy per molecule than glucose? Explain your answer in terms of the electrons extracted during the process of cellular respiration. 2. A rare, frameshift genetic mutation can alter the structure of the Pyruvate Dehydrogenase Complex such that it no longer functions within the cell. Describe what parts of the process of cellular respiration would be impacted due to this non- functional enzyme. 3. The citric acid cycle functions to completely oxidize glucose in the...
Explain why two genes 50 or more map units apart on a genetic map can only result in a maximum of 50% recombinant gametes in two point cross. To answer this, ask yourself what percentage of recombinant gametes would result if the probability of crossing over in a tetrad involving these genes were 100%, as it would be if the two genes are 50 or more map units apart.
Why were futures originally created? A. For market speculators to gain more leverage B. As part of a fortune-telling cult C. To hedge against uncertainty D. As a counterpart for options contracts with expiration dates in the future What is the Contract Size? A. The total amount represented by one contract B. The length of the technical specifications sheet each party signs C. How far in the future the contract matures D. How many of the contract is issued on...
3. Early experiments aimed at sequencing DNA were designed to mimic approaches used for proteins. Enzymatic end group analysis was a particularly popular method because wide variety of nucleases was available. However, while end group analysis with enzymes like aminopeptidase provided sequence information for the first 20 to 30 amino acids of a protein, end group analysis with nucleases like spleen phosphodiesterase failed to reach even those modest lengths. Briefly explain why nuclease-based end group anaylsis is so limited.
Please explain why the answer wrong
