After translation,a protein may undergo structural changes called __________ modifications.
A) splicing
B) posttranscriptional
C) posttranslational
D) polyribosomal
E) secretory

Question

Quizplus · Accepted Answer

Posttranslational modifications refer to structural changes that occur to a protein after it has been translated from RNA. This includes modifications such as phosphorylation, glycosylation, and proteolytic cleavage. Splicing (A) refers to the removal of introns from RNA molecules, while posttranscriptional (B) refers to modifications that occur to mRNA before it is fully processed. Polyribosomal (D) refers to the process of multiple ribosomes binding to a single mRNA molecule, while secretory (E) refers to the pathway in which proteins are transported out of the cell.
