"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. " - How are okazaki fragments formed
