Verified step by step guidance1
Understand the role of each enzyme listed in the context of DNA replication.
Helicase is responsible for unwinding the DNA double helix, creating two single strands that serve as templates for replication.
Ligase is involved in joining Okazaki fragments on the lagging strand, sealing nicks in the sugar-phosphate backbone of DNA.
DNA polymerase is the enzyme that synthesizes new DNA strands by adding nucleotides complementary to the template strand.
Amylase is an enzyme that breaks down starches into sugars and is not involved in the process of DNA replication.
