What is Protein biosynthesis?
'''Protein biosynthesis ([[synthesis]])''' is when [[cell (biology)|cells]] build [[protein]]s. The term is sometimes used to refer only to protein [[translation (genetics)|translation]] but more often it refers to a multi-step process. [[Amino acid]]s are either synthesised or eaten in food. Then, after the [[transcription (genetics)|transcription]] of [[polypeptide]] [[genes]], the amino acids are put together. This is done by [[translation (genetics)|translation]] and [[RNA splicing]] which produces [[messenger RNA]]s. The splicing process produces the final proteins, which then fold up into their [[protein structure]]. Then they can function. The plural is used here because, with most genes, the splicing process produces more than one final working protein. One particular [[Drosophila]] gene (DSCAM) can be alternatively spliced into 38,000 different [[mRNA]].<ref name=Schmucker2000>{{cite journal| author = Schmucker D. | display-authors = etal| year = 2000| title = Drosophila Dscam is an axon guidance receptor exhibiting extraordinary molecular diversity| journal = Cell| volume = 101| issue = 6| pages = 671–684| pmid = 10892653| doi = 10.1016/S0092-8674(00)80878-8| s2cid = 13829976}}</ref> Protein biosynthesis differs between [[prokaryote]]s and [[eukaryote]]s, though parts of the process are the same in both. == References == {{Reflist}} == Other websites == * [http://www.scienceaid.co.uk/biology/genetics/proteinsynthesis.html Science aid: protein synthesis] {{Webarchive|url=https://web.archive.org/web/20070212165430/http://www.scienceaid.co.uk/biology/genetics/proteinsynthesis.html |date=2007-02-12 }} For high school * [http://www.accessexcellence.org/AB/GG/protein_synthesis.html Protein synthesis] * [http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/T/Transcription.html Transcription] {{Webarchive|url=https://web.archive.org/web/20061214090229/http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/T/Transcription.html |date=2006-12-14 }} *: [http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/T
