DNA is the very basic structure of someone traits. That's is where everything about a person from their eye color to how tall they will be is explained. It is unique like a finger print. There is no one in the world that shares the same DNA. Not even identical twins have the same DNA. Sometimes similar but never the same.
DNA carries the "codes" that communicate what traits will be formed. The nucleotides in DNA are read and transcribed into mRNA which travels ot of the cells nucleus and then goes to a ribosome. In the ribosome, tRNA matches to mRNA with its anticodon. Each of the tRNA molecules are carrying an amino acid which are all connected by the ribosome to create an amino acid chain, which is a protein, which are traits in an organisms.
