What do developmental regulatory genes do?
Select one:
a. decide details of animal construction
b. mute active genes
c. turn genes on
Homework Answers
Ans: Genes encoding transcription factors or signaling proteins that are expressed during development in specific spatiotemporal patterns and, by regulating the expression of other genes, control patterning and morphogenesis of specific body parts are called Developmental regulatory genes. So from the definition we can say that these genes decide details of animal construction

(1) Explain the specific role of homeotic genes in controlling animal development; what specific aspect of development is controlled by homeotic genes, and how do they achieve this? (5 pts) (ii) Explain why a mutation to a homeotic gene can be an important macroevolutionary event. Your response should include a clear discussion of what macroevolution means and the type of evolutionary change associated with macroevolution (as opposed to microevolution), and why mutations to homeotic genes can result in macroevolution.

1. The catabolic Activation Protein (CAP) is a regulatory protein associated with several carbohydrate metabolism operons in bacteria. a) Describe the activation / inactivation of CAP and how it affects the transcription of downstream genes. Include any important co-factors required for CAP where it binds DNA, and under what circumstance is it active / inactive. Do not discuss the downstream genes, refer to them as 'active' or 'inactive'. b) What is the relationship of the enzyme adenyl cyclase to the...
