Question

Allows for an easier break of HydrUGLIO 5. Describe the role of each of the following in bacterial DNA replication: DnaA, DnaB, topoisom single-stranded binding proteins, DnaG, DNA polymerase III, DNA polymerase I, DNA ligase. recruit helicase proteins • DnaA: proteins bind to each other and the DnaA boxes • DnaB: (helicases) move in a 5' to 3' direction and unzip the double helix Topoisomerase: catalyze controlled cleavage and rejoining of DNA that prevents over-winding relieves torsional tension single-stranded binding proteins: bind the separated DNA strands to prevent them from re-annealing DnaG (primase): a specialized RNA polymerase synthesizes needed primers joins DnaA, DnaB, and DnaC at oric DNA polymerase III: responsible for most of the DNA replication builds new strands 5'-3' DNA polymerase 1: exonuclease digests the RNA primers and replaces them with DNA DNA ligase: seals nick at 5' end of replaced primer 6. Draw a replication fork, with directionality, and place each of the above proteins in your illustration L i boridan
