During DNA replication, the **lagging strand** is synthesised:
AContinuously in 5'→3' direction
BContinuously in 3'→5' direction
CDiscontinuously in short Okazaki fragments (5'→3' direction)
DIt is not synthesised — only the leading strand replicates
Answer & Solution
Correct answer: C. Discontinuously in short Okazaki fragments (5'→3' direction)
DNA polymerase only adds nucleotides 5'→3'. On the lagging template (oriented 5'→3' running with the replication fork), this can't be continuous — so synthesis proceeds in short 5'→3' Okazaki fragments away from the fork, later joined by DNA ligase. Leading strand is continuous.
