So we used our codons to basically create our proteins. There are 64 codons and only 20 amino acids, which means that the different codons can code for the same exact amino acid. And this makes our genetic code degenerate. Therefore, if a point mutation occurs, if a point mutation occurs and causes a change in the codon, but the new codon still codes for the same exact amino acid, no change in protein structure will take place because our sequence of amino acids will be exactly the same. Now, to see what that actually means, let's take a look at the following diagram. So, let's suppose this is our DNA template that we're going to use to basically synthesize our mRNA molecule.
