Homeotic Genes Contain a Homeobox Sequence That Is Highly Conserved

question 27

Multiple Choice

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
