The structure of DNA is a double helix as given by Watson and Crick.
It contains four bases ie, Adenine, Guanine, Cytosine and Thymine.
Adenine always pairs with Thymine by three hydrogen bonds and Guanine is always pairs with Cytosine by two hydrogen bonds.
Note that in RNA the base Thymine is replaced by Uracil.
