Okazaki fragments are produced during DNA replication on which strand?

ALeading strand (continuous synthesis)
BLagging strand (discontinuous synthesis)
CBoth strands equally during replication
DOnly on the parental strand initially
Answer & Solution
Correct answer: B. Lagging strand (discontinuous synthesis)
The lagging strand is synthesised in DISCONTINUOUS OKAZAKI FRAGMENTS (because DNA polymerase only works 5' to 3', but the lagging strand template runs 5' to 3' away from the fork). DNA ligase joins the fragments.
