Question Detail
Question
The enzyme that breaks hydrogens bond between double strands DNA during replication is: a. restriction enzymes b. helicase c. DNA polymerase d. DNA ligase
Correct Answer
Option B is the correct answer.
Detailed Explanation
Helicase is the enzyme that unwinds the DNA double helix by breaking the hydrogen bonds between the base pairs, separating the two strands. DNA polymerase synthesizes new DNA, and ligase joins fragments.
Hint
Think 'helicopter' unwinding a rope.
