DNA polymerase delta - Answer-eukaryote: completes replication on the *lagging* strand; binds more tightly to DNA sliding clamp nucleotide and base excision repair Single strand binding proteins - Answer-Bind to the unpaired DNA strands, keeping them from re-pairing topoisomerase 1 - Answer-Making single-stranded DNA breaks to relieve supercoiling at origin topoisomerase 2 - Answer-An enzyme that breaks both strands (a DNA double helix), rotates the ends, and seals the break. *USES ATP*...

topoisomerase 1 → Making single-stranded DNA breaks to relieve supercoiling at origin topoisomerase 2 → An enzyme that breaks both strands (a DNA double helix), rotates the ends, and seals the break. → *USES ATP* DNA gyrase → type of topoisomerase 2 DNA helicase → An enzyme that unwinds the DNA double helix at origin Primase → RNA polymerase: An enzyme that joins RNA nucleotides to make the primer using the parental DNA strand as a template. Single strand binding prote...
