उत्तर
After an mRNA has been translated and leaves the ribosome or polysome, it is degraded.
Explanation:
Once an mRNA molecule has completed its role in translation, it is typically degraded by enzymes called ribonucleases (RNases). This breakdown is a crucial regulatory step, as it prevents the cell from overproducing specific proteins and allows it to quickly shift its metabolic focus in response to new environmental signals. The resulting individual nucleotides are then recycled to synthesise new RNA molecules.
