Mapuroteni ndiwo ma biomolecules makuru, kana macromolecules, anoumbwa neketani imwe kana anopfuura akareba eamino acid residues. Mapuroteni anoita mabasa akawanda mukati mezvipenyu, kusanganisira catalyzing metabolic reactions, DNA replication, kupindura kune zvinokurudzira, kupa chimiro kumasero uye zvipenyu, uye kutakura mamorekuru kubva kune imwe nzvimbo kuenda kune imwe. Mapuroteni anosiyana kubva kune mumwe nemumwe kunyanya mukuteedzana kwavo kweamino acids, iyo inotungamirirwa ne nucleotide sequence yejenasi yavo, uye iyo inowanzoita kuti mapuroteni apindike muchimiro chakasarudzika chetatu chinotarisa chiitiko chayo. Mubvunzo: Ndeipi rimwe zita remapuroteni makuru?
