Homeotic genes contain a homeobox sequence that is highly conserved among very diversespecies. The homeobox is the code for that domain of a protein that binds to DNA in aregulatory 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 non homeotic genes.D) That all organisms must have homeotic genes.E) That all organisms must have homeobox containing genes.
