Taw qhia txog saw hlau polypeptide
Tus tub xa xov RNA (mRNA) hloov pauv los ntawm qee ntu ntawm deoxyribonucleic acid (DNA) hauv lub keeb los ntawm cov keeb ntawm nuclear nkag mus rau hauv cytoplasm thiab sib txuas nrog cov ribosome (Ribosome). Protein synthesis yuav siv qhov chaw hauv lub ribosome. Thaum cov protein pib pib tsim tawm, ua ntej lub ribosome yog sib xyaw nrog mRNA, lub ribosome tau txuas rau ib kawg (pib qhov chaw) ntawm mRNA, thiab tom qab ntawd txav mus raws mRNA los ntawm 5 ′ 3 ′ kev taw qhia (thaum tsiv lub ribosome rau tom ntej sai sai, lwm qhov Nws tau sib xyaw dua, yog li mRNA tuaj yeem muaj ntau lub ribosomes hauv uake).
