Detailed Solution

The DNA-dependent DNA polymerases catalyze polymerization only in one direction, that is 5' to 3'. This creates some additional complications in the replicating fork for synthesis of the template, which is in the 3' to 5' direction. Thus, the strand is synthesized discontinuously.

Since discontinuous stand synthesis requires the addition of a primer every time, it is composed of many short fragments which are a combination of ribonucleotides and deoxy ribonucleotides called okazaki fragments.
