In both prokaryotic and eukaryotic cells, multiple ribosomes may be attached to a single mRNA, generating a structure called a polyribosome.
-In a polyribosome, the polypeptides associated with which ribosomes will be the longest?
A) Those at the 5' end of mRNA
B) Those at the 3' end of mRNA
C) Those in the middle of mRNA
D) All polypeptides will be the same length.

Question

Quizplus · Accepted Answer

In a polyribosome, ribosomes closer to the 3' end of the mRNA have been translating for a longer time and thus have synthesized longer polypeptides compared to those near the 5' end.
