Answer:
DNA is the genetic code for your body. DNA tells what color your hair is going to be or what skin pigment you will have-- how much melanin your skin will produce. It even tells what kind of nose you will have and what your lips will be like. It makes you who you are. Chromosomes, strands of DNA packed together, also tell if you will be Autistic or have some genetic disease. Some diseases are caused by the mutation of DNA, but not all, such as AIDs.
