Hace 3 días · Su artículo de 1950 fue decisivo para que Watson y Crick resolvieran el enigma de la estructura del ADN tan sólo unos años después. De hecho, fue una conversación que Chargaff mantuvo con Watson y Crick en 1952 la que les llevó a deducir la estructura de doble hélice del ADN. Como era de esperar, Chargaff protestó cuando Watson y Crick ...
Hace 2 días · Narración. El ADN, o ácido desoxirribonucleico, es la molécula que contiene la información genética de todos los seres vivos, incluso algunos virus. El nombre viene de su estructura. El ADN tiene una parte central con un azúcar y un fosfato, a la que se enlazan unas moléculas llamadas bases. La desoxirribosa se refiere al azúcar, y el ...
Hace 1 día · Rosalind Elsie Franklin (25 July 1920 – 16 April 1958) [1] was a British chemist and X-ray crystallographer whose work was central to the understanding of the molecular structures of DNA (deoxyribonucleic acid), RNA (ribonucleic acid), viruses, coal, and graphite. [2] Although her works on coal and viruses were appreciated in her lifetime ...
Hace 2 días · Erwin Chargaff developed and published observations now known as Chargaff's rules, stating that in DNA from any species of any organism, the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.

Hace 2 días · Watson and Crick’s contemporaneous discovery of the double helix structure of DNA (1953) consolidated the work of a number of scientists, particularly Erwin Chargaff’s (1950) discovery that the nucleotide composition of DNA varies among species, and that the same nucleotides do not repeat in the same order, as previously thought.
