DNA gyrase - Wikipedia

WebOnce the chromosome has been completely replicated, the two DNA copies move into two different cells during cell division. The process of DNA replication can be summarized as follows: DNA unwinds at the origin of replication. Helicase opens up the DNA-forming replication forks; these are extended bidirectionally. WebIn the absence of the replication checkpoint kinase S. cerevisiae Rad53/S. pombe Cds1, cells treated with HU suffer replication fork collapse and replication proteins including polymerases are lost from the fork, leading to the model that the replication kinases recruited to the fork act on replication proteins to arrest replication and promote ... they\u0027re 6u

WebReplication in prokaryotes starts from a sequence found on the chromosome called the origin of replication—the point at which the DNA opens up. Helicase opens up the DNA double helix, resulting in the formation of the replication fork. Single-strand binding proteins bind to the single-stranded DNA near the replication fork to keep the fork open.
