WebApr 10, 2024 · DNA replication enzymes have the ability to quicken reactions and build up or break down the items that they act upon. Below listed are the enzymes involved in DNA replication. DNA Polymerase III: It is known as the builder. This enzyme replicates DNA molecules actually building a new strand of DNA. WebThe replication complex is the group of proteins that help synthesize the new DNA strands. A replication unit is any chunk of DNA that is capable of being replicated — e.g. a plasmid with an origin of replication (ORI) is a replication unit. Alternatively, this can also mean a region of DNA that is replicated together.
