Example of a question:
Question 1: What is the function of DNA polymerase in DNA replication?
a) It unwinds the DNA double helix
b) It adds new nucleotides to the growing DNA strand
c) It proofreads the newly synthesized DNA strand
d) It stabilizes the DNA replication fork
Detailed Explanation: The correct answer is B. DNA polymerase is responsible for adding new nucleotides to the growing DNA strand during replication. It is an enzyme that catalyzes the formation of phosphodiester bonds between adjacent nucleotides, resulting in the synthesis of a complementary strand. This process ensures accurate replication of genetic information. For example, in DNA replication, DNA polymerase adds nucleotides to the leading and lagging strands, ensuring the fidelity of the genetic code. In a complex scenario, mutations in DNA polymerase can lead to errors in DNA replication, causing genetic diseases or cancer.
