All eight Drosophila Hox genes encode proteins containing a highly conserved 60-amino-acid domain called the:
A)hox box.
B)homeodomain.
C)hox domain.
D)heterodomain.
E)chromodomain.

Question

Quizplus · Accepted Answer

The highly conserved domain found in all eight Drosophila Hox genes is known as the homeodomain. This domain is approximately 60 amino acids in length and is responsible for binding to specific DNA sequences to regulate gene expression. The terms hox domain and hox box are commonly used in the context of Hox genes but are not accurate descriptions of the conserved domain within these genes. The terms heterodomain and chromodomain refer to unrelated protein domains that are not present in Drosophila Hox proteins.
