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?

#SCPH06 I Botany
  1. That homeotic genes are selectively expressed over developmental time.

  2. That a homeobox containing gene has to be a developmental regulator.

  3. That homeoboxes cannot be expressed in non-homeotic genes.

  4. That all organisms must have homeotic genes.
