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.
