Question

Quizplus · Accepted Answer

The addition of a poly-A tail occurs after transcription, during mRNA processing. This modification helps protect the mRNA from degradation and also facilitates its export from the nucleus to the cytoplasm for translation. Replication and translocation do not involve mRNA and occur in different parts of the cell. Translation and termination occur after the addition of the poly-A tail.
