Following post-translational modification, any misfolded protein will be destroyed by
A) ubiquitin.
B) chaperones.
C) methylation.
D) ribonucleases.

Question

Quizplus · Accepted Answer

Misfolded proteins are recognized by chaperones and marked with ubiquitin for degradation. The ubiquitin-marked proteins are then degraded by proteasomes. Methylation is a type of post-translational modification that affects gene expression by adding a methyl group to DNA or RNA. Ribonucleases are enzymes that break down RNA molecules and are not involved in the degradation of misfolded proteins.
