Watson and Cricks model, the double helix, showed that the base pairs bind together in the centre of the DNA molecule. Therefore because the bases are found in pairs, there must be equal amounts of each. This explained Chargaff's rules - the number of guanine is equal to the number of cytosine and that the number of thymine is equal to the number of adenine - because they are found as pairs.
Watson and Crick's Name for the twisted ladder of DNA
Chargaff discovered that in DNA the percentages of adenine and thymine were the same, and the percentages of cytosine and guanine are the same. This led to the idea of base-pairing between adenine and thymine, and cytosine and guanine.
Sir James Watson and Sir Francis Crick first described the molecular structure of DNA correctly. They not only mentioned the fact that DNA is a helical structure, but also described how the constituting molecules are arranged in the helix. The base-pairing, sugar-phosphate backbone were first described by Watson and Crick.

The role of creativity in scientific discovery is best illustrated by Watson and cricks ball and stick model of DNA.
