Born 21 Mar 1932.
American molecular biologist who changed into provided a share (with Paul Berg and Frederick Sanger) of the Nobel Prize for Chemistry in 1980 for his improvement of a technique for figuring out the collection of nucleotide hyperlinks withinside the chainlike molecules of nucleic acids (DNA and RNA). Everything from micro organism up, he says, except a few viruses, stocks a few comparable DNA. There are many genes, in lots of species, that create proteins which have the equal biochemical function. In a few cases, the ones genes are identical; every so often they may be very comparable. Thus, all residing matters probable hint lower back to a unmarried ancestral DNA. Whereas many human genes are much like the ones in different lifestyles forms, every species developed sufficient specific genes to differentiate itself.
