In biologyconserved sequences are similar or identical sequences that occur withinnucleic acid sequences (such as RNA and DNA sequences), proteinsequences, protein structures or polymeric carbohydrates across species(orthologous sequences) or within different molecules produced by thesame organism (paralogous sequences). In the case of cross speciesconservation, this indicates that a particular sequence may have beenmaintained by evolution despite speciation. The further back up thephylogenetic tree a particular conserved sequence may occur the morehighly conserved it is said to be. It is widely believed that mutationin a highly conserved region leads to a non-viable life form, or a formthat is eliminated through natural selection.…
