What does it mean for DNA strands to be antiparallel?

They run in the same direction, both 5' to 3'.

Why is the lagging strand synthesized in fragments during DNA replication?

Helicase unwinds DNA too quickly for continuous synthesis.

Primase can only place primers in short bursts.

DNA polymerase can only add nucleotides to the 3' end of a growing strand.

Ligase needs gaps to join the new DNA segments.
