Chapter 8, Problem 7Q
Summary Introduction

To determine: How does the cleavage of a repressor at a site between DNA-binding domain and dimerization domain result in its dissociation from DNA.

Introduction:

Lysogeny also known as prophage stage refers to integration of phage in the host genome where it replicates with the host DNA over many generations. To maintain this state, the lambda (λ) repressor represses the virus’s lytic genes. Repressor molecules contain an N-terminal domain that binds to DNA and a C-terminal dimerization domain. They bind as dimers to critical sites on the lambda (λ) genome.

If using animals in medical experiments could save human lives, is it ethical to do so? In your answer, apply at least one ethical theory in support of your position.
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. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?
You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
