In bidirectional, none of the two ends will be stationary and both will be moving. Therefore, bidirectional replication involves replicating DNA in two directions at the same time resulting in a leading strand and a lagging strand. Is replication unidirectional?
WebSep 12, 2024 · DNA synthesis of daughter strands starts at discrete sites, termed replication origins, and proceeds in a bidirectional manner until all genomic DNA is replicated. Despite the fundamental nature of these events, organisms have evolved surprisingly divergent strategies that control replication onset. WebBidirectional Replication: In circular DNA of bacteria and linear DNA of eukaryotes, DNA replication proceeds bidirectionarlly starting from a fixed origin of replication. The two replication forks move in opposite directions. Bidirectional replication may have multiple replication forks. They speed up the process of replication.
