Problem

A eukaryotic mRNA has the following sequence: 5'-AUGCCCCGAACCUCAAAGUGA-3'. How many codons does it contain, and how many amino acids have been coded?

Solution

The translation of an mRNA to its corresponding polypeptide uses the genetic code as guide to the correct amino acid that codes for a particular sequence. These particular sequences that code for an amino acid are known as codons, a three-base sequence of mRNA.
