There isn't one.
Mitochondria won't decode the corrupted mRNA and it will be broken down into constituent parts that are reused by the body.
Edit: Oops, ribosomes, not mitochondria.

> Given the central role of RNA in many fundamental biological processes, including translation and splicing, changes to its chemical composition can have a detrimental impact on cellular fitness, with some evidence suggesting that RNA damage has roles in diseases such as neurodegenerative disorders. We are only just beginning to learn about how cells cope with RNA damage, with recent studies revealing the existence of quality-control processes that are capable of recognizing and degrading or repairing damaged RNA.
(The actual estimate is 10 million billion...)
Edit following my other edit: each cell has something like 10 million ribosomes.
