Questions on Post Transcriptional Modification with Answers (PDF)

Post-transcriptional modifications are processes that modify pre-mRNA into mature mRNA after transcription in eukaryotic cells. These modifications include the addition of a 5′ cap, splicing to remove introns, and the addition of a poly-A tail at the 3′ end. These changes protect mRNA from degradation, aid in its export from the nucleus, and ensure proper translation into proteins. These modifications are crucial for regulating gene expression and ensuring accurate protein synthesis. This is an MCQ questions on Post Transcriptional Modification.
