Mutations

ID #1242

In the last exam material we learned that in Eukaryotic cells each mRNA is copied numerous times to make an X amount of a type of protein. But if there is a mutation and you produce a non-functional protein- does the cell recognize that right away and degrade the mRNA? Or do non-functional proteins continue to be made? If so, does it start cluttering up the cell?


Good question! It's actually more likely that the non-functional protein made from the "bad" mRNA will be tagged for destruction and degraded. mRNAs have a rather finite "life expectancy" anyway, so if it's not recognized as being "bad," it will be gone before too long anyway.
