DNA Replication Quiz

What shape is DNA described as having?

• Single helix

• Double helix

• Triple helix

• Quadruple helix

Which enzyme is responsible for unzipping the DNA strands during replication?

• DNA polymerase

• Primase

• Helicase

• Ligase

How is the new DNA strand that is synthesized continuously called?

• Lagging strand

• Leading strand

• Okazaki fragment

• Helix strand

How is DNA replication described in terms of the strands in the new DNA molecule?

• Semi-conservative

• Fully conservative

• Non-conservative

• Discontinuous

Which enzyme is responsible for adding nucleotides to the growing DNA strand during replication?

• Ligase

• Helicase

• Primase

• DNA polymerase

What is the function of RNA primase during DNA replication?

• It unwinds the DNA helix

• It seals the gaps between the Okazaki fragments

• Adds RNA primers

• It adds nucleotides to the growing DNA strand

What are the short fragments of DNA synthesized on the lagging strand called?

• Leading fragments

• Helix fragments

• Okazaki fragments

• Primase fragments

What is the role of DNA polymerase during DNA replication?

• Unwinding the DNA helix

• Sealing the gaps between the Okazaki fragments

• Adding RNA primers

• Adding nucleotides to the growing DNA stranding a 5' to 3' direction

What is the significance of the semi-conservative model of DNA replication?

• Both strands of the DNA molecule are conserved

• One strand of the DNA molecule is conserved

• Each daughter DNA molecule consists of one parental and one newly synthesized strand

• None of the original DNA strands are conserved in the daughter DNA molecules

Which enzyme is responsible for sealing the gaps between the Okazaki fragments during DNA replication?

• DNA polymerase

• Helicase

• Primase

• Ligase
