Well, we know what the first three nucleotides are because that's the primer. So we have T, G and C. So the question is, what are these remaining nucleotides here? Well, let's try to use the following setup to base determine what the sequence is. So we know that the farther down along our page, the the smaller our fragment is and the closer the nucleotide sequence is to the beginning. And the fragment all the way at the bottom basically describes this right over here. So that means the first nucleotide following the primer is the one lowest at the bottom.
