Chapter 20, Problem 5P

Consider the even skipped regulatory sequences in Figure 18.9 .

a. How are the sharp boundaries of expression of eve stripe 2 formed?

b. Consider the binding sites for gap proteins and Bicoid in the stripe 2 enhancer module. What sites are occupied in parasegments 2, 3, and 4 , and how does this result in expression or no expression?

c. Explain what you expect to see happen to even-skipped stripe 2 if it is expressed in a Krüppel mutant background. A hunchback mutant background? A giant mutant background? A bicoid mutant background?

MyoD is a transcriptional activator that turns on theexpression of several muscle-specific genes in humancells. The Id gene product inhibits MyoD action.a. One possibility is that the Id protein directly represses the expression of these muscle-specificgenes. Explain how Id would function if it were arepressor.b. Another possibility is that Id inhibits musclespecific gene transcription indirectly, by preventingMyoD function. Explain how Id could function asan indirect repressor.c. Suppose you know the amino acid sequence ofthe Id protein. How might this information supportthe hypothesis in part (a) or in part (b)?
Describe the common signal transduction event that is perturbed by cancer-promoting mutations in the genes encoding RAS and NF-1. Why are mutations in RAS more commonly found in cancers than mutations in NF-1?
