On the upper lagging strand, synthesis is discontinuous, since new RNA primers must be added as opening of the replication fork continues to expose new template. In order for DNA polymerase to synthesize a complete new strand of DNA, it requires a template to determine the order of bases on the new strand, a 3-OH end to add more nucleotides onto, and the full set of four kinds of nucleotides (A,C,T,G) if they are needed to complement the template strand. Okazaki fragments are formed on lagging strands, initiated by the creation of a new RNA primer by the primosome.
