List three different types of posttranslational modifications that may happen to a protein and the significance of each in the context of protein function.

Hi everyone here we have a question asking which of the following is not a post translational modification. So what is a post translational modification? This is a modification that occurs after a protein has been produced. So let's look at our answers. We have a phosphor relation, phosphor relation happens after a protein has been produced. So A is incorrect. We have be like oscillation. Like oscillation happens after a protein has been produced. So B is incorrect. See polly a dental ation polyu ventilation happens before the protein has been produced. It is when the pre M. RNA is cleaved at the poly A site and a poly a tail is added. So C. Is our correct answer. Here. Lastly we have deep methylation and it occurs after the protein has been produced. So that is incorrect. So again, our answer here is see Polly A desolation. Thank you for watching. Bye.
