Honors Biology Semester 2 Final Exam with Complete Solutions What is the role of helicase in DNA replication? Helicase unwinds the DNA double helix by breaking hydrogen bonds between base pairs, allowing replication to begin. How does complementary base pairing ensure accuracy during DNA replication? Complementary base pairing (A with T, C with G) ensures that each new strand is an exact copy of the original template. What is a codon, and how is it related to DNA? A codon is ...
