post-transcriptional control

Post-transcriptional control refers to the regulation of gene expression after DNA has been transcribed into messenger RNA (mRNA). This process determines whether the mRNA is stable, how efficiently it is translated into a protein, or if it is degraded. These controls allow cells to quickly adjust protein production in response to changing needs or conditions. Mechanisms include modifying mRNA stability, splicing, transport, and initiation of translation. Overall, post-transcriptional control is a key way cells fine-tune gene expression beyond the initial transcription step, ensuring proteins are produced at the right time and amount.
