[Effect of exogenous DNAses on various stages of DNA replication in microorganisms].
Effect of DNAase 1 on DNA synthesis and cell division was studied in microorganisms deficient in some stages of DNA replication initiation. The DNA synthesis induced by exogenous DNAase was found to be a replicative origin since it was registered from the "origin" of chromosomal replication under the conditions of initiation of proteins functioning. Stimulation of DNA synthesis in bacterial cells having mutations in DNA B and DNA G genes by DNAase 1 indicates that exogenous DNAases participate in replicative fork during the DNA synthesis.
