mRNA stability

mRNA stability refers to how long messenger RNA molecules last inside a cell before they break down. mRNA carries genetic instructions from DNA to produce proteins. If an mRNA is stable, it remains intact longer, allowing more protein to be made; if it’s unstable, it’s quickly degraded, reducing protein production. Factors like chemical modifications, cellular environment, and specific sequences can influence mRNA stability. This regulation helps cells control how much of a protein is made, ensuring proper function and response to changes. In essence, mRNA stability is a vital mechanism for managing gene expression efficiently.
