Question
Chapter 13.6, Problem 3MC
Summary Introduction
To determine:
The basis of using a molecular clock to determine when two species diverged from a common ancestor.
Introduction:
Molecular clock used to calculate the time when two species diverged. Molecular clock can calculate the rate of mutations that occur long ago. DNA is a biological molecule that functions as a ‘clock’. If DNA can be used as a molecular clock, biologists are able to identify the rate of mutation in a gene and the count of differences in the DNA sequence for that gene in two species.

9. Aerobic respiration of one lipid molecule. The lipid is composed of one glycerol molecule connected to two
fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure
below. Use the information below to determine how much ATP will be produced from the glycerol part of
the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally
put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your
total number of ATP produced per lipid. Assume no other carbon source is available.

- You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds.
