What DNA is: DNA is a self replicating organism that exists in almost every living thing. It is the main component of chromosomes and is the carrier of genetic information.

What DNA does: It contains all the instructions need for and animal to develop, survive and reproduce. To do this sequences that must be converted into proteins.
