E) All of the above are correct

Question

Quizplus · Accepted Answer

Translational frame shifting can indeed result in the synthesis of multiple polypeptides from a single mRNA, has been observed in cells infected by retroviruses, and involves a +1 or -1 change in the reading frame of an mRNA. This mechanism allows for the production of different proteins from the same mRNA sequence by altering the frame in which ribosomes read the mRNA.
