Duba wurin da ke ƙasa sannan ka amsa tambayar daga baya a cikin harshe ɗaya kamar yadda wurin yake:  Passage: Proteasomes wani bangare ne na babban tsari wanda kwayoyin halitta ke tsara yawan sunadarai na musamman kuma suna lalata sunadarai marasa kyau. Ana yiwa sunadarai alama don lalacewa tare da karamin furotin da ake kira ubiquitin. Ana amfani da enzymes da ake kira ubiquitin ligases don amsa alamar. Da zarar an yi wa furotin alama tare da kwayar ubiquitin guda ɗaya, wannan alama ce ga sauran ligases don haɗa ƙarin kwayoyin ubiquitin. Sakamakon shine sarkar polyubiquitin wanda ke ɗaure da proteasome, yana ba shi damar lalata furotin da aka yiwa alama.
