Continue Reading. The double helix shape of DNA molecules consists of two rails and steps that link the rails together.
X-ray crystallography provided the final clue that the DNA molecule is a double helix, shaped like a twisted ladder. In 1953, the race to determine how these pieces fit together in a three-dimensional structure was won by James Watson and Francis Crick at the Cavendish Laboratory in Cambridge, England.They showed that alternating deoxyribose and phosphate molecules form the twisted uprights of the DNA ladder.The rungs of the ladder are formed by complementary pairs of nitrogen bases â A always paired with T and G always paired with C.-ray crystallography provided the final clue that the DNA molecule is a double helix, shaped like a twisted ladder.
