Efforts to understand how proteins are encoded began after DNA's structure was discovered in 1953. The key discoverers, English biophysicist Francis Crick and American biologist James Watson, working together at the Cavendish Laboratory of the University of Cambridge, hypothesied that information flows from DNA and that there is a link between DNA and proteins.

DNA sequences are linked together in a gene pool by gene conversion events. Insertion of an interspersed DNA element breaks this linkage, allowing independent evolution of a new gene. The interspersed repeat is an isolating mechanism enabling new genes to evolve without interference from the progenitor gene. Because insertion of an interspersed ...
Band length in this diagram is proportional to base-pair length. This type of ideogram is generally used in genome browsers (e.g. Ensembl , UCSC Genome Browser ). G-banding patterns of human chromosome 3 in three different resolutions (400, [ 14 ] 550 [ 15 ] and 850 [ 3 ] ).
The total length of capillaries in the human body is not 100,000 km. That figure comes from a 1929 book by August Krogh, who used an unrealistically large model person and an inaccurately high density of capillaries. The true number is believed to be between 9,000 and 19,000 km. [301]
This is a list of Ig Nobel Prize winners from 1991 to the present day. [1]A parody of the Nobel Prizes, the Ig Nobel Prizes are awarded each year in mid-September, around the time the recipients of the genuine Nobel Prizes are announced, for ten achievements that "first make people laugh, and then make them think".
