[{'content': 'False statements are \nSelect and explain. \nA. Multiple origins of replication are possible for bacteria, B. DNA replication proceeds in one direction, C. Lagging strand stick by RNA primase, D. All of these', 'role': 'user'}, {'content': "Answer: D \nExplanation: In leading strands, DNA is synthesized continuously by DNA polymerase III.\nBacteria have only single origins of replication as their DNA is circular.\nIn lagging strand, Okazaki fragments are sticked by ligase, not by primase.\nOption 'c' is a tricky one. DNA replication proceeds in 5' → 3' on both strand. But as both parent strands are antiparallel, synthesis on leading strand is toward the replication fork, while synthesis on lagging strand is away from replication form (i.e. in opposite direction).", 'role': 'assistant'}]
