Nirenberg and Matthaei experiment another. These experiments helped pave the way for the discovery of the structure of DNA. In 1953, with the help of Maurice Wilkins and Rosalind Franklin’s X-ray crystallography, James Watson and Francis Crick proposed DNA is structured as a double helix. In the 1960s, one main DNA mystery scientists needed to figure out was the number of bases found in each code word, or codon, during transcription. Scientists knew there was a total of four bases (guanine, cytosine, adenine, and thymine). They also knew that were 20 known amino acids. George Gamow suggested that the genetic code was made of
Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid "Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid" was the first article published to describe the discovery of the double helix structure of DNA, using X-ray diffraction and the mathematics of a helix transform. It was published by Francis Crick and James D. Watson in the scientific journal "Nature" on pages 737–738 of its 171st volume (dated 25 April 1953). This article is often termed a "pearl" of science because it is brief and contains the answer to a fundamental mystery about living organisms. This mystery
