Correct Answer: Option C
Explanation
Bacterial (prokaryotic) DNA replication features: (1) Semi-conservative — each daughter cell receives one parental and one newly synthesised strand (Meselson-Stahl, 1958). (2) Semi-discontinuous — leading strand synthesised continuously, lagging strand synthesised as Okazaki fragments (1–2 kb in bacteria). (3) Chain growth 5'→3' — DNA polymerase can only add nucleotides to a free 3'-OH. (4) BIDIRECTIONAL (NOT unidirectional) — two replication forks travel in OPPOSITE directions from the single origin (oriC) in E. coli. Each fork is replicated by a replisome (DnaB helicase, primase DnaG, DNA Pol III holoenzyme). Replication terminates at Ter sequences where Tus protein blocks fork progression. Eukaryotic replication is also bidirectional from multiple origins.
