mRNA degradation

mRNA degradation is the natural process where the cell breaks down messenger RNA (mRNA) molecules after they’ve served their purpose of delivering instructions from DNA to produce proteins. This breakdown helps regulate protein production, ensuring the cell maintains proper levels of each protein. Factors like enzymes called nucleases recognize specific sequences or structures in the mRNA and cleave it into smaller pieces. Once broken down, the components are recycled for new mRNA synthesis or other cell functions. This process is essential for cell health, adaptability, and proper gene expression regulation.
