And we're going to discuss what the DNA polymerase needs to actually synthesize that DNA molecule during the replication process. So let's begin by looking at the general equation that describes how DNA polymerase actually works. So let's suppose inside our cell, we are replicating the DNA molecule and so far we have N number of nucleotides in our DNA polynucleotide chain. So we have N number of nucleotides in the DNA molecule. Now, if we want to add one more nucleotide, we actually have to take the dNTP, the deoxy nucleotide triphosphate, and add it onto the DNA molecule in the process. What we do is we form a phosphodiather bond between this molecule and this molecule.
