In prokaryotic cells the synthesis reactions of DNA, RNA and proteins are intricately coupled as there are no subcellular compartments. Thus replication, transcription and translation occur ... WebbOther proteins are then recruited to start the replication process (). A helicase using the energy from ATP hydrolysis opens up the DNA helix. Replication forks are formed at each replication origin as the DNA unwinds. The opening of the double helix causes over-winding, or supercoiling, in the DNA ahead of the replication fork.
