WitrynaThe strand of DNA at the replication fork that is continuously synthesized. A protein complex that encircles the DNA double helix and binds on the back of DNA polymerase, to keep it firmly bound to the DNA while it is moving. Aids in processivity. Falls off at the completion of each Okazaki fragment. Witryna16 gru 2024 · The gap between the two DNA fragments is sealed by DNA ligase, which helps in the formation of phosphodiester bonds. Table 14.4.1. 1 summarizes the enzymes involved in prokaryotic DNA replication and the functions of each. Table 14.4.1. 1: Prokaryotic DNA Replication: Enzymes and Their Function. Enzyme/protein.
