What happens to mRNA's after translation. Do they get degraded?
After translation, mRNA's (messenger RNA) serve as a template for protein synthesis by carrying the genetic information from DNA to the ribosomes.
After translation, mRNA's undergo post-transcriptional modifications such as capping, polyadenylation, and splicing to form mature mRNA's that can be transported out of the nucleus for translation.
Yes, mRNA's before translation contain introns (non-coding regions) that are removed during splicing to form mature mRNA's after translation. Additionally, the 5' cap and poly-A tail are added during post-transcriptional processing.
The lifespan of mRNA's after translation can vary depending on the specific mRNA and the cellular conditions. Some mRNA's can last for minutes, while others can last for days before being degraded. This is an important mechanism for regulating gene expression.
Yes, some mRNA's can undergo additional modifications such as alternative splicing, which can produce different versions of the same protein from a single gene. mRNA's can also be targeted for degradation by various mechanisms to regulate protein levels in the cell.
