Which of the following enzymes below plays a role in unzipping the DNA helix and separating them into two identical strands a. topoisomerase b. primase c. Helicase d. ligase

The correct answer is c. Helicase.<br /><br />Helicase is an enzyme that plays a crucial role in unzipping the DNA helix and separating the two strands. During DNA replication, helicase unwinds the double-stranded DNA molecule, breaking the hydrogen bonds between the base pairs. This unwinding creates a replication fork, allowing other enzymes to access the individual strands and synthesize new complementary strands.<br /><br />Topoisomerase, on the other hand, helps to relieve the tension created by the unwinding of the DNA helix by cutting, unwinding, and rejoining the DNA strands.<br /><br />Primase is an enzyme that synthesizes a short RNA primer, which serves as a starting point for DNA synthesis.<br /><br />Ligase is an enzyme that joins two fragments of DNA together by forming phosphodiester bonds between them.
