DNA Replication DNA Replication DNA replication is the biological process by which a cell copies its DNA before cell division. It ensures that each daughter cell receives an identical copy of genetic information. 1 / 18 DNA replication is: Conservative Dispersive Semi-conservative Random 2 / 18 Semi-conservative replication was proven by: Watson & Crick Avery & MacLeod Matthew Meselson & Franklin Stahl Hershey & Chase 3 / 18 DNA replication occurs during: G1 phase S phase G2 phase M phase 4 / 18 DNA synthesis occurs in which direction? 3' → 5' 5' → 3' Both Random 5 / 18 The starting site of replication is: Promoter Enhancer Origin of replication Terminator 6 / 18 In bacteria, origin of replication is: ARS OriC TATA box Telomere 7 / 18 Replication forks move: Unidirectionally Bidirectionally Circularly Randomly 8 / 18 Replication requires: RNA template Protein template DNA template Lipid template 9 / 18 Leading strand synthesis is: Discontinuous Continuous Reverse Random 10 / 18 Lagging strand synthesis produces: Primers Okazaki fragments Telomeres Introns 11 / 18 Okazaki fragments were discovered by: Watson Reiji Okazaki Kornberg Chargaff 12 / 18 Replication bubble contains: One fork Two forks Three forks No fork 13 / 18 DNA polymerase requires: ATP Primer Lipase RNA polymerase 14 / 18 The template strand is read: 5'→3' 3'→5' Randomly Bidirectionally 15 / 18 Initiator protein in bacteria: DnaA DNA pol I Ligase Helicase 16 / 18 Helicase function: Synthesizes primer Digest Hydrogen bond Joins fragments Adds nucleotides 17 / 18 Enzyme that relieves supercoiling: Ligase Primase Topoisomerase Single Strand Binding Protein 18 / 18 Single-strand binding proteins: Cut DNA Join DNA Add nucleotides Stabilize single strands Your score isThe average score is 94% 0% Restart quiz
