And once we expose these two molecules another type of enzyme known as primates which is basically an RNA polymerase binds to each one of these two individual and exposed single stranded DNA molecules and it adds a set or a series of nucleotides that together are known as RNA primer. So primase adds a series of nucleotides onto these two exposed single stranded DNA molecules and these are known as RNA primer. An RNA primer basically acts as a signal and signals for another protein known as DNA polymerase to actually bind to that primer region and initiate DNA replication. So basically the DNA polymerase bind to the primer region and adds individual nucleotides one by one extending our synthesized strand known as the daughter strand. So basically the single stranded DNA molecule that is being synthesized is known as the daughter strand. But the actual original DNA single stranded molecule that is used as a template to synthesize the new molecule is known as the parent strand.
