WebUnderstanding: • Helicase unwinds the double helix and separates the two strands by breaking hydrogen bonds. • DNA polymerase links nucleotides together to form a new … WebSinglestrand binding proteins attach to each strand of the uncoiled DNA to keep them separate. As helicase unwinds the DNA, it forces the double-helix in front of it to twist. A group of enzymes, called topoisomerases, break and rejoin the double helix, allowing the twists to unravel and preventing the formation of knots.

WebC. Ligase joins the DNA strand by catalyzing the formation of a phosphodiester bond between the adjacent bases. D. Topoisomerase helps in relieving the tension created during the unwinding of DNA. Hence, the enzyme that catalyzes the separation of DNA strands during DNA replication is Helicase. So, the correct answer is 'Helicase'. WebDNA helicase unwinds the double helix, so (A) is true and therefore incorrect. Choice (B), DNA ligase seals the discontinuous Okazaki fragments, is also true. Eliminate it. In the presence of DNA polymerase, DNA strands always grow in the 5' to 3' direction as complementary bases attach. Therefore, (D) is also incorrect.
