1. (a)How many amino acids are found in the polypeptide when the mRNA is translated? mRNA 5 - AAUAUGCGGAUGCCCGAA -3     4     5     6     7 (b) "In this mutation, the UGG codon is replaced with UGA."     missense mutation     nonsense mutation     silent mutation     frameshift mutation

The eukaryotic mature mRNA sequence will be translated into a polypeptide that is _____ amino acids long (hint remember to "be a ribosome" and scan for the AUG and look out for stop codons!).   5’-CCATTCAUGUUUGGUGGCUAACCA-3’
