What happens to mRNA after transcription?

Explanation:
After transcription, the RNA transcript typically undergoes RNA processing. In many cells this means adding a 5' cap, removing introns and joining exons (splicing), and adding a poly-A tail at the 3' end. These steps produce a mature mRNA that is stable, can be exported from the nucleus, and is ready for efficient translation into protein. Translation happens after processing, so it isn’t the immediate fate right after transcription. DNA replication is a different process that duplicats the genome, and RNA degradation can occur for some messages, but the standard immediate outcome for a newly made mRNA is processing into a mature form.
