So basically, let's suppose between the 7th and the 8th nucleotide on the DNA antisense strand, we insert our cytosine nucleotide. So now our DNA strand consists of ten nucleotides and not nine. So we have the mutated DNA antisense strand. 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.
