#1 Bozeman Biology - DNA Replication Quiz

What is the primary function of DNA replication?

• To create genetic diversity
• To make a copy of DNA for cell division
• To repair damaged DNA
• To facilitate protein synthesis

During which phase of the cell cycle does DNA replication occur?

• G1 phase
• S phase
• G2 phase
• M phase

What is the role of helicase in DNA replication?

• To add nucleotides
• To unwind the DNA double helix
• To repair DNA errors
• To synthesize RNA primers

Which of the following statements best describes the semiconservative model of DNA replication?

• Both strands of DNA are completely new
• One strand is old and one strand is new
• Both strands are identical to the original
• DNA replication occurs in a random manner

What is the function of DNA polymerase during replication?

• To unwind the DNA
• To synthesize RNA primers
• To add nucleotides to the growing DNA strand
• To ligate DNA fragments

What is the significance of the Meselson-Stahl experiment in the context of DNA replication?

• It demonstrated the role of helicase
• It provided evidence for the semi-conservative model
• It showed how DNA polymerase functions
• It identified the structure of DNA

Which of the following best describes the lagging strand during DNA replication?

• It is synthesized continuously
• It is synthesized in short fragments
• It is synthesized in the same direction as the replication fork
• It does not require RNA primers

How does the directionality of DNA polymerase affect replication?

• It can synthesize DNA in both directions
• It can only add nucleotides to the 5' end
• It can only add nucleotides to the 3' end
• It does not affect replication direction

What role do RNA primers play in DNA replication?

• They provide a template for DNA synthesis
• They are the main component of the DNA strand
• They initiate the synthesis of the leading strand
• They are necessary for the activity of helicase

Which enzyme is responsible for synthesizing new DNA strands during replication?

• Helicase
• Ligase
• DNA polymerase
• Primase
