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

Which enzyme is responsible for adding nucleotides?

• Helicase

• DNA Polymerase

• Ligase

• Primase

Which enzyme is responsible binding the nucleotides into place?

• Helicase

• DNA Polymerase

• Ligase

• Primase
