A.1) Given what you know about genome size why might you expect neutral substitutions to happen more slowly in viruses than in bacteria?
A.2) Why might neutral substitutions actually happen faster in viruses than bacteria?
Answer:- Neutral substitutions to happen more slowly in viruses
than in bacteria because virusia a acellular organism that contain
DNA/RNA as genome.
- mutations that are induced by polymerase
excision repair on mispaired bases and mutated
dsDNA, but that are unable to fix such mistakes
in dsRNA or RNA–DNA heteroduplexes14.
2. Because mostly virus have DNA as gemetic material and protein coat.

a)Why are transmembrane proteins mostly comprised of alpha helices? b)More generally, what might happen if you substituted a tryosine for a cystein in the active site of a protein
Try to answer each question in about 50 words. 1. What is the limitation on what bacteria can utilize as nutrients? 2. A farm soil is heavily limed for two consecutive years to bring the pH from 5.2 to 6.5. What changes do you expect in the bacteria community? 3. How is soluble Fe2+ restored into the soil solution at pH 5? 4. A microcolony of bacteria has a plasmid it acquired from the environment. This plasmid confers a new...
8. Given what you know about substitution reactions of square planar complexes, explain what would happen in the reaction (Pt(NH3)4]2+ + Cl → Pt(NH3)3CIJ* + NH3 if the entering group were changed from Cl to Br. How would the rate be affected? Write the mechanism for the reaction (be sure to designate a rate determining step) and draw a reaction coordinate diagram.
What would happen to you if you fell out of a spaceship, naked? Hollywood has given us many portrayals of this event, with the skin boiling or instantly freezing; but what actually happens, and what effect is most severe? The lack of oxygen is one: we know that humans can only survive a number of minutes without breathing. But there are a number of other factors to consider. (A) Assume a human is a 2 m tall cylinder of 75...
1. Sketch a graph of what you might expect for a triprotic acid in terms of pH and volume of sodium hydroxide added 2. Explain why the second equivalence point in a diprotic acid is expected to be more easily determined graphically 3. Calculate the molarity of a sodium hydroxide solution if 25.00 mL of 0.100 M maleic acid requires 22.10 mL of NaOH to reach the endpoint.
Based on what you know about the structure of humic material (HM), explain why it is more likely that HM molecules in solution have net negative charge rather than net positive charge.
POST-LAB QUESTIONS 1. What would happen if you added more than 5 mL of yeast solution to the H2O2? 2. What would happen if you added more than 5 mL of H2O2 to the 5 mL of yeast solution?
1) What types of amino acids would you expect to find in the membrane-spanning region(s) of a membrane protein? Why? 2) What is the connection between “surface area-to-volume ratio” and cell size? Why are unicellular organisms much more limited by this (in general terms, why do they have to be small?)? 3) What is the difference between general transcription factors and transcriptional regulators? If you compared one of each type, which would you expect to be more abundant in...
