"Wow!" said Doug, "How do you manage that?"

DNA structure

In 1953, the Nature journal published the structure of DNA, as suggested in a one-page article by James Watson and Francis Crick. Their work earned the pair of scientists a Nobel Prize in 1962. The structure explained how DNA passed heriditary information from cell to cell, and from generation to generation. “This structure has two helical chains each coiled around the same axis... Both chains follow right-handed helices... The novel feature of the structure is the manner in which the two chains are held together by purine and pyrimidine bases... They are joined together in pairs, a single base from one chain being hydrogen-bonded to a single base from the other chain, so that the two lie side by side with identical z-co-ordinates.”«[Image: DNA as illustrated in the Nature article.]
