Deoxyribonucleic acid (DNA)

We all inherit traits from both our parents. These traits are passed down from parent to child by the genes we get from our parents. These genes are carried on a long molecule chain called DeoxyriboNucleic Acid, or DNA. DNA is made up of a sequence of smaller molecules called amino acids and forms a double helix.
