Answer: The discontinuous aspect of replication of dna in vivo is caused by  the 5' to 3' polarity restriction.

Explanation:

That DNA is antiparallel means that the two strands of DNA have opposite chemical polarity, or, stated another way, their sugar-phosphate backbones run in opposite directions.  Direction of, and in reference to, DNA molecules is then specified relative to these carbons.
