Double-Helix+and+base-pairing

The structure of DNA is in a double helix.The two strands of DNA are wrapped around each other. The strands are held together by hydrogen bonds between cytosine-guanine and adenine-thymine. Two hydrogen bonds are formed between adenine and thymine, and three hydrogen bonds are formed between cytosine and guanine. This explained the cause of Chargaff's Rule



//Discovery// The structure of DNA was discovered by James Watson and Francis Crick.They received assistance from Rosalind Franklin's X-ray photographs.
