Which enzyme is responsible for unwinding the DNA double helix at the replication fork by breaking hydrogen bonds between nitrogenous bases?
Show answer and explanation
Correct answer: DNA Helicase
DNA Helicase uses energy from ATP hydrolysis to separate the two parental strands of DNA. This creates the replication fork, allowing other enzymes access to the single-stranded templates.
