'S e poilimear a tha ann aig a bheil mìltean de dh'aonadan a tha bunachadh air searbhagan amino ann an iom-obrachadh co-dhlùthachaidh a th' ann. Lorgar pròtainean air feadh na cuirp, agus falt, ìnean is fèithean dèanta orra. Tha beirmearan cuideachd nam pròtainean.
Nuair a bhios feum air pròtain anns a' chuirp, seo foillseachadh ghineachan anns a bheil dà ìre: tar-sgrìobhadh agus eadar-theangachadh. Ann an tar-sgrìobhadh bidh polymerase RNA a' dèanamh leth-bhreac de DNA mar RNA teachdaire (mRNA). Ann an eadar-theangachadh bidh an ribosome a' dèanamh sèine de pheptidean a-rèir an fhiosrachaidh anns an mRNA.
