Now once we actually unwind our double stranded DNA molecule and we expose these single stranded DNA regions another type of molecule known as primates which is basically an RNA polymerase creates primers or RNA primers. Remember, an RNA primer is basically a sequence of nucleotides that are needed for DNA polymerase to bind and to begin the synthesis of our daughter strands. Now, how exactly does DNA polymerase actually synthesize our daughter strand? Well, basically DNA polymerase acts as a catalyst. It catalyzes the formation of our phosphol digester bonds. So it takes the nucleotides that are found in the environment so these are free nucleotides and attaches these nucleotides together via phosphol diaster bonds or phosphol diaster linkages.
