Question:
What are human homeodomains?


Replies:
All animals have a 180 base pair (60 amino acid) sequence that is highly conserved and codes for regulatory proteins that control embryonic development. These are called HOX genes in mammals and control the basic layout of the body. They say "put an eye here", or "put legs here", etc. They don't say what KIND of eye, just that an eye should be put in a certain place.
