Verified
Removal of introns, addition of a poly-A tail, and addition of a 5' cap are all events that occur during ____.
A) protein folding
B) transcription
C) replication
D) post-transcriptional modification
E) translation
Introns
Non-coding sequences of DNA within a gene that are removed during RNA processing before translation into proteins.
Post-transcriptional Modification
The process of chemical changes to RNA transcripts after synthesis, affecting their stability, localization, and translation into proteins.
Poly-A Tail
A stretch of adenine nucleotides added to the 3' end of a newly synthesized pre-mRNA molecule in eukaryotic cells, protecting the mRNA from degradation and aiding in its export from the nucleus.
- Recognize the components and processes involved in the modification and processing of RNA.

Final Answer :
D
Explanation :
Removal of introns, addition of a poly-A tail, and addition of a 5' cap are all modifications that occur after transcription, during post-transcriptional processing. This process prepares the mRNA for translation by removing non-coding regions and adding stability features to the molecule.
