DNA Replication

The enzyme that unzips the DNA to prepare for replication

• helicase
• replicase
• polymerase
• synthase

DNA replication results in two DNA molecules,

• each one with two original strands

• one with two new strands and the other with two original strands

Which enzyme fixes the Okazaki fragments?

• Helicase

• Polymerase

• Ligase
