Match each enzyme with its corresponding function in bacterial DNA replication. Helicase Single strand binding proteins DNA polymerase III DNA polymerase I DNA ligase Primase Gyrase A. Main "work horse" of DNA replication. Attaches nucleotides to growing DNA strand. B. Creates a short RNA primer. C. Removes primers and replaces with DNA nucleotides. D. Breaks hydrogen bonds, separating DNA strands. E. Topoisomerase that relieves tension created by unwinding DNA. F. Forms phosphodiester bond between two existing DNA strands. G. Prevents formation of secondary structures in the template DNA. QUESTION 2 During DNA replication, new nucleotides are attached to the ________ of the last nucleotide of the growing DNA strand. 5' phosphate group 2' OH group 3' OH group nitrogenous base 3' phosphate group 5' OH group

Match the enzyme or protein with the correct description of its activity in bacterial DNA replication. Chains most nucleotides together during DNA replication DNA gyrase or Topoisomerase DNA Polymerase III DNA Helicase Single stranded binding proteins DNA Polymerase I DNA Primase DNA Polymerase II RNA Polymerase Sits in the replication fork while breaking hydrogen bonds between base pairs DNA gyrase or Topoisomerase DNA Polymerase III DNA Helicase Single stranded binding proteins DNA Polymerase I DNA Primase DNA Polymerase II RNA Polymerase Functions ahead of the replication fork to relieve excess supercoiling as the DNA opens up DNA gyrase or Topoisomerase DNA Polymerase III DNA Helicase Single stranded binding proteins DNA Polymerase I DNA Primase DNA Polymerase II RNA Polymerase Coats the single stranded regions of DNA so they don't base pair internally

Match the enzymes to their role in the DNA replication process. RNA primase 1. ligase 2. helicase 3. polymerase 4. topoisomerase 5. RNA primase 1. unwinds the DNA molecule 2. synthesizes the complementary daughter strands 3. synthesizes RNA primer at the initiation point 4. creates nicks ahead of the replication fork to relieve tension from unwinding 5. joins the Okazaki fragments together
