A homeotic gene codes for a(n) ________ protein, a sequence of 60 amino acids, sets of which determine the genes to be turned on during development.
A) induction
B) morphogenesis
C) growth
D) regulatory
E) homeodomain

Question

Quizplus · Accepted Answer

The sequence of 60 amino acids referred to in the question is the homeodomain, which is found in proteins coded for by homeotic genes. These proteins are regulatory in nature and are involved in determining the identity of body segments during development. Therefore, the best choice is E) homeodomain.
