Hace 2 días · The chemical DNA was first discovered in 1869, but its role in genetic inheritance was not demonstrated until 1943. In 1953 James Watson and Francis Crick , aided by the work of biophysicists Rosalind Franklin and Maurice Wilkins , determined that the structure of DNA is a double-helix polymer , a spiral consisting of two DNA strands wound ...

Hace 1 día · DNA was first isolated by the Swiss physician Friedrich Miescher who, in 1869, discovered a microscopic substance in the pus of discarded surgical bandages. As it resided in the nuclei of cells, he called it "nuclein".
Hace 3 días · After joining King's College London in 1951 as a research associate, Franklin discovered some key properties of DNA, which eventually facilitated the correct description of the double helix structure of DNA.
Hace 4 días · DNA model built by Crick and Watson in 1953, in the Science Museum, London. In mid-March 1953, Watson and Crick deduced the double helix structure of DNA. Crucial to their discovery were the experimental data collected at King's College London—mainly by Rosalind Franklin for which they did not provide proper attribution.
11 de jun. de 2024 · James Watson, American geneticist and biophysicist who played a crucial role in the discovery of the molecular structure of deoxyribonucleic acid (DNA), the substance that is the basis of heredity. For this accomplishment he was awarded a share of the 1962 Nobel Prize for Physiology or Medicine.
