DNA Replication Quiz

What is the primary function of DNA during replication?

• To form proteins

• To create RNA molecules

• To serve as a template for new strands

• To break down nucleotides

Which enzyme is responsible for unwinding the DNA strands?

• RNA polymerase

• Helicase

• DNA polymerase

• Ligase

What role does Topoisomerase play in DNA replication?

• It synthesizes new DNA strands

• It prevents supercoiling of DNA

• It seals DNA fragments

• It adds RNA primers

Why is the lagging strand synthesized in fragments?

• Because it is more stable

• Because DNA polymerase can only synthesize in one direction

• Because it contains more nucleotides

• Because it is shorter than the leading strand

What is the final result of DNA replication?

• Two identical RNA molecules

• Two identical DNA molecules

• Two different DNA molecules

• One new DNA and one new RNA molecule
