Question

Quizplus · Accepted Answer

The 5' cap is necessary for translational initiation, as it serves as a recognition site for the ribosome to bind and begin translating the mRNA strand. Therefore, adding or removing the 5' cap can regulate gene activity at the level of translation. RNA splicing and 3' polyadenylation occur after transcription and do not directly involve the 5' cap. Translational termination occurs at the end of the mRNA sequence and is not directly affected by the presence or absence of the 5' cap.
