- DNA polymerases are processive, which means that they remain tightly associated with the template strand while moving rapidly and adding nucleotides to the growing daughter stand. Which piece of the replication machinery accounts for this characteristic? Helicase Sliding Clamp Single Stranded Binding Protein PrimaseDefine DNA replication/synthesis and semiconservative replication. In addition, describe and/or define the role(s) of each of the following in the process of DNA replication/synthesis: DNA template strand, 5’ and 3’ ends, DNA helicase, DNA polymerase, single-strand binding proteins, topoisomerase, primase, Okazaki fragments, leading strand and lagging strand.Which of the following enzymes can break, and rejoin, phosphodiester bonds during the normal DNA replication process in the chromosomes of E. coli cells? single-stranded binding proteins RNA polymerase topoisomerase DNA helicase DNA ligase
