In the year of 1953, Watson and Crick worked out the 3-D structure of DNA, beginning from X-ray diffraction photographs taken through Wilkins and Franklin. They decreased which DNA is composed of two strands wound round each other to form a double helix with the bases on the inside and the sugar-phosphate back- bones on the outside. In the double helix that is represent in the figure, the two DNA standards are organized in an antiparallel arrangement example for the two strands run in opposite directions one is orientated 3'→5' and the other standard is orientated 5'→3'. The bases of the two strands produced hydrogen bonds to every other; the pairs with T and G pairs with C. This is called as complementary base pairing. Thus a large two-ringed purine is paired with a smaller single-ringed pyrimidine and the two bases fit neatly in the gap among the sugar-phosphate strands and handle the right spacing. There would be insufficient space for two large purines to pair and too much space for two pyrimidines to pair that would be too far apart to bond. The A:T and G:C base pairing also maximizes the number of effective hydrogen bonds which can form between the bases; there are three hydrogen bonds between every G:C base pair and two hydrogen bonds between each A:T base pair. Thus A: T and G: C base pairs form the most stable conformation both from steric considerations and from the point of view of maximizing hydrogen bond formation.
