Deoxyribonucleic Acid (DNA)
This is my genetics project I created explaining the history of DNA and how it was discovered. Deoxyribonucleic Acid (DNA) has four structures. The four structures are adenine, thymine, cytosine, and guanine. Erwin Chargaff discovered that the four structures are all equal. Adenine and thymine are one pair as well as guanine and cytosine being another pair. The four structures make up the double helix. From his discovery Chargaff proposed two rules. The rules identify the structures being all equal and the compositions of DNA.
