Function of gyrase in dna replication
WebGyrase has multiple roles in DNA replication, recombination, and transcription. Its participation in replication and recombination is briefly summarized here; the complex relations between supercoiling and transcription are discussed later. Gyrase is apparently needed in replication systems for initiation, chain elongation, and termination.
