We have GCG AG, where this is a cytosine that has been inserted between the 7th and the 8th DNA nucleotide. So let's see what kind of polypeptide sequence of amino acids we're actually going to form. So when this molecule is transcribed, we form this mutated mRNA molecule. The reason it's mutated is because it contains this guanine between the second and the third amino and the third nucleotide. So the G becomes a C, the complement of A is our U, the C becomes a G, the T becomes an A, C becomes A-G-G becomes a C, the A becomes a U and so forth. So this is a five end, this is our three end.
