DNA Replication Quiz

What is the role of helicase during the initiation stage of DNA replication?

• It adds nucleotides to the DNA strand.

• It checks for errors in the DNA sequence.

• It separates the two DNA strands.

• It synthesizes RNA primers.

During the elongation stage, what is the primary function of DNA polymerase?

• To terminate the replication process.

• To add nucleotides to the growing DNA strand.

• To separate the DNA strands.

• To unwind the DNA helix.

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

• It uses only one strand of the original DNA.

• It ensures that each new DNA molecule is identical to the original.

• It allows for faster replication of DNA.

• It prevents errors during replication.

Why is it crucial for DNA replication to be precise?

• To allow for mutations to occur.

• To ensure that new cells have the same genetic material as the parent cell.

• To speed up the cell division process.

• To create genetic diversity.

What mechanism helps correct errors during DNA replication?

• DNA proofreading process

• DNA ligase function

• RNA primer synthesis

• Helicase activity
