DNA Double Helix
The DNA double helix was identified by Watson and Crick in the late 1950's as being the most likely structure for DNA. This structure has been verified in many different ways and its identification is recognized as one of the most significant breakthroughs in modern science.
In geometry a double helix (plural helices) typically consists of two congruent helices with the same axis, differing by a translation along the axis, which may or may not be half-way. In molecular biology, the double helix refers to the structure of DNA. The structure of DNA was first published in the journal Nature by James D. Watson and Francis Crick in 1953, based upon data from Maurice Wilkins and Rosalind Franklin. Crick, Wilkins and Watson each received the Nobel Prize for their contributions to the discovery.
