A mechanism which is an example of post-transcriptional gene regulation is: B. alternative splicing of exons in an RNA transcript.
Translation refers to a cellular process through which a genetic code from a sequence of messenger ribonucleic acid (mRNA) molecule is translated (decoded) to a specific sequence of amino acids, during the synthesis of protein.
Post-translational gene regulation can be defined as the the control of gene expression at the ribonucleic acid (RNA) level, after the transcription of a messenger ribonucleic acid (mRNA) molecule and before it is translated (decoded) into a protein.
This ultimately implies that, post-translational gene regulation can occur in living cells at any stage after transcription.
Furthermore, the alternative splicing of exons in an ribonucleic acid (RNA) transcript is a mechanism which is an example of post-transcriptional gene regulation because it results in the production of a matured ribonucleic acid (RNA) and multiple messenger ribonucleic acid (mRNA) isoforms.
