DNA Replication Quiz

What is the primary function of DNA during replication?

• To form proteins

• To serve as a template for creating identical DNA molecules

• To convert into RNA

• To break down into nucleotides

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

• RNA polymerase

• Ligase

• DNA polymerase

• Helicase

What role does Topoisomerase play in DNA replication?

• It prevents supercoiling of DNA

• It adds RNA primers

• It seals DNA fragments

• It synthesizes new DNA strands

Why is the lagging strand synthesized in fragments?

• Because it does not require a primer

• Because DNA polymerase can only synthesize in the 5' to 3' direction

• Because it is shorter than the leading strand

• Because it is made of RNA

What is the final result of DNA replication?

• Two different DNA molecules

• One single-stranded DNA molecule

• Two identical double-stranded DNA molecules

• Two RNA molecules
