This is our antisense strand. So basically, on the five end, we have the C, then the A, the C, the G, the C, and on the three N, we have the g nucleotide. Now, if we actually use this DNA molecule and transcription takes place, then we synthesize the following mRNA molecule where the C becomes a G, the A becomes a U, the C becomes a G, the G becomes a C. The C becomes a g and the g becomes a C. So this is our sequence of nucleotides on the mRNA molecule that will be used to synthesize our protein. Now, if we look on our genetic code, we see that CGC stands for the amino acid arginine, while the gug stands for our amino acid, the valine. So let's suppose a point mutation takes place, and we basically replace the fourth nucleotide guanine with this nucleotide cytosine. So basically, this is our point mutation.
