Watson & Crick came long after the time of Chargaff and were probably very well aware of Chargaff's rule. That is that the percentage of adenine was equal to the percentage of thymine and the percentage of guanine was equal to the percentage of cytosine. They were probably aware of complementary base pairs because without them the DNA molecule would not retain the standard radius of 1nm. Base pairing is important because one purine (which is bigger) and one pyrimidine (which is smaller) will always bond together. If two purines were to bond together they radius of the DNA would be inconsistent.

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.

DNA is a molecule that looks like a twisted ladder. It's "rungs" are made of 4 nucleotide bases. Their names are: Adenine, Guanine, Cytosine, and Thymine. Each base only matches with the corresponding base. Adenine is always together with Thymine. Cytosine is always with Guanine. These combinations can be put in any order as long as they are matched with the matching base.
