1. Eukaryotic messenger RNA includes a poly A tail. When the 1. Eukaryotic messenger RNA includes a poly A tail. When the poly(A) tail is less than approximately 30 nucleotides in length, explain why the messenger RNA no longer is protected from nuclease digestion. 2. Explain the reasons why a mutation in one of the genes that codes for a protein needed for mismatch repair would lead to elevated mutation rates in other genes. Biology Science cell biologyBIOL 240
