Homeotic genes contain a homeobox sequence that is highly conserved among very diverse species. The homeobox is the code for that domain of a protein that binds to DNA in a regulatory developmental process. Which of the following would you then expect?
A) that homeotic genes are selectively expressed over developmental time
B) that a homeobox-containing gene has to be a developmental regulator
C) that homeoboxes cannot be expressed in nonhomeotic genes
D) that all organisms must have homeotic genes
E) that all organisms must have homeobox-containing genes
