DNA A 1 of 11 Where does DNA A bind? 9-mer sequence 2 of 11 What is special about the 13-mer region? It is A-T rich 3 of 11 Which 2 proteins must be together to start replication? DNA helicase and DNA primase 4 of 11 Which protein prevents replication from starting again too soon? Seq A 5 of 11 What is the name given to GATC sites that have only one methylated strand? Hemi-methylated 6 of 11 What is the main DNA polymerase for DNA replication? 3 7 of 11 What is the role of topoisomerases? Prevents supercoiling of DNA and separates daughter DNA 8 of 11 What is the role of DNA helicase? Unzips parental DNA so it can be read and replicated 9 of 11 What is the role of DNA ligase? Joins ends of Chromosome together 10 of 11 What is the name given to the separation of bacterial DNA by topoisomerase 2? Decatenation 11 of 11
