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

Please match the correct answers. DNA Polymerase III Not match with any others Lagging Strands Leading Strands Polytene Chromosomes Ribosomes tRNAs Promoters Alternative splicing Transcription factors [ Choose ] Primary replication enzyme in eukaryotes Nucleotide sequences that serve as recognition sites for transcription machinery DNA strand synthesized continuously in the direction of the replication fork Primary replication enzyme in Bacteria DNA strand synthesized discontinuously in the opposite direction of the replication fork Carrier of amino acids Site of the protein synthesis DNA of paired homologs undergoes many rounds of replication without strand separation or cytoplasmic division Generates different forms of mRNA from identical pre-mRNA Bind to enhancers or promoter elements to control transcription initiation

Match the DNA replication enzyme with the description: Puts in short, complementary RNA primer Breaks hydrogen bonded base pairs Adds complementary DNA nucleotides to the growing DNA strand Connects chunks of replicated DNA on the lagging strand replaces RNA primers with DNA bases primase DNA Polymerase (I - a different DNA polymerase) helicase DNA Polymerase (III - the primary polymerase) ligase

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
