Watson-Crick model
Wat·son-Crick model W0058300 (wät′sən-krĭk′)n. A three-dimensional model of the DNA molecule, consisting of two complementary polynucleotide strands wound in the form of a double helix and joined in a ladderlike fashion by hydrogen bonds between the purine and pyrimidine bases.
[After James Dewey Watson and Francis Henry Compton Crick.]Watson-Crick model
Watson-Crick model (wät′sən-krĭk′)n. A three-dimensional model of the DNA molecule, consisting of two complementary polynucleotide strands wound in the form of a double helix and joined in a ladderlike fashion by hydrogen bonds between the purine and pyrimidine bases.Watson-Crick model The double helix concept of the DNA molecule, proposed by two workers in Cambridge in 1953, which triggered off a revolution in biology and medicine and led to an explosive succession of advances in genetics. (James D. Watson, b. 1928, American molecular biologist; and Francis H. C. Crick, b. 1916, English biochemist, now neurophysiologist). |
