Covalent linkage to what small,highly-conserved protein marks proteins for destruction?
A)chaperonin
B)actin
C)ubiquitin
D)cyclin
E)dystrophin

Question

Quizplus · Accepted Answer

The small, highly-conserved protein that marks proteins for destruction is called ubiquitin. It is covalently linked to the targeted protein via a process called ubiquitination, which leads to degradation of the protein. This process is important in regulating various cellular processes, including protein turnover and cell signaling.
