And once we unwind, what happens is the DNA polymerase shown in red basically binds onto our single stranded DNA molecules and it creates those phosphodia ester bonds by combining, by attaching our nucleotides together. So first we form the RNA primer by using our primase enzyme and this is shown in purple. And then we basically create those other nucleotides by using our RNA polymerase or DNA polymerase. And notice that for the case of the parent strand that runs from the three to the five direction, the DNA polymerase basically creates the nucleotides begin with the five and ending with the three end. So we see that DNA polymerase has no problem synthesizing our daughter's strand on the parent molecule that runs three to five. However, what happens in this case for the parent strand that begins with the five and ends with the three?
