Chapter 17, Problem 3Q
Summary Introduction

To review:

The level of activity of the enzyme coded by ‘A’ allele compared to the enzyme coded by ‘G’ allele.

Given:

In the given experiment, the rate of metabolism and drug concentration after 12 hours of administration is correlated with different genotypes of single nucleotide polymorphisms (SNP) 5689. The results are shown as given in the diagram below:

Life: The Science of Biology, Chapter 17, Problem 3Q

Introduction:

The metabolism of drug is effective in people with genotype GG where drug concentration in the blood is around 70. The drug concentration for the genotype AG is around 100 and it is around 130 for AA genotype. It is assumed that the SNP 5689 is present in a gene, which encodes an enzyme. This enzyme breaks down the drug.

(a) Is it biologically advantageous that DNAis stable? Why or why not? (b) Is it biologically advantageous thatRNA is unstable? Why or why not?
Assume that a DNA sequencing reaction is carried out, except that the four different dideoxyribonucleoside triphosphates are modified so that each contains a covalently attached dye of a different color (which does not interfere with its incorporation into the DNA chain). What would the products be if you added a mixture of all four of these labeled dideoxyribonucleoside triphosphates along with the four unlabeled deoxyribonucleoside triphosphates into a single sequencing reaction? What would the results look like if you electrophoresed these products in a single lane of a gel?
Based on the information in as shown, which single-nucleotide mutationevent is more likely: Arg-to-His, or Arg-to-Ser? Explain.
