DNA Structure_Revisiting The Watson-Crick Double Helix | PDF James watson and francis crick has made a major contribution in 1953 to the development of the structure of dna. they combined the physical and chemical data and proposed dna as double helical twisted molecules connected together by hydrogen bonds. Watson and crick developed their ideas about genetic replication in a second article in nature, published on may 30, 1953. the two had shown that in dna, form is function: the double stranded molecule could both produce exact copies of itself and carry genetic instructions.

The Discovery Of DNA Double Helix Structure : Watson & Crick's Model ... Francis crick and james watson are pivotal figures in 20th century biology. in 1953, they unveiled the double helix structure of deoxyribonucleic acid (dna), a discovery that fundamentally reshaped the understanding of life. J.d.watson and f.h.c. crick (1953) combined the physical and chemical data, and proposed a double helix model for dna molecule. this model is widely accepted. according to this model, the dna molecule consists of two strands which are connected together by hydrogen bonds and helically twisted. “the structure of dna,” by james d. watson and francis crick, described the ladderlike double helical configuration of the molecule, with external ribose phosphate chains connected by rungs composed of pairs of amino acids. After realizing the structural similarity of the a:t and c:g pairs, watson and crick soon produced their double helix model of dna with the hydrogen bonds at the core of the helix providing a way to unzip the two complementary strands for easy replication: the last key requirement for a likely model of the genetic molecule.

In 1953, james watson and francis crick made a groundbreaking contribution to the understanding of dna structure. by combining physical and chemical data, they proposed a model for dna as a double helix, a twisted molecule consisting of two complementary strands held together by hydrogen bonds. Deoxyribonucleic acid (dna) is a double stranded, helical molecule. it consists of two sugar phosphate backbones on the outside, held together by hydrogen bonds between pairs of nitrogenous bases on the inside. In the early 1950s, the race to discover dna was on. at cambridge university, graduate student francis crick and research fellow james watson (b. 1928) had become interested, impressed especially. James watson and francis crick’s discovery of dna’s structure is significant because it revealed the double helix model, which explained how genetic information is stored and transmitted in living organisms.
