Problem Set 3 Name: Answer Key Genetics 0350 Martens Due February 21, 2008 at 2:30 am 15 points total 1) 3 points. The molecule 5-bromouracil (5BU) is an analog of thymine, pairing with adenine. It also pairs occasionally with guanine. We have described how 5-bromouracil can promote a change of an A-T base pair to a G-C base pair. Starting with the G-C base pair below, diagram how 5-bromouracil can also promote a change of a G-C base pair to an A-T base pair. Make sure to keep the orientation of your DNA strands the same throughout your drawing (in other words, A-T T-A). 2) 6 points. In a diploid organism, you have six mutants that each contain a single homozygous recessive mutation. Complementation tests indicate that the six mutations lie in three different genes. Complete the following table where “+” indicates complementation and “-” indicates no complementation by filling in the open squares. 1
