Detailed explanation-1: -Accurate DNA replication depends on the ability of DNA polymerases to discriminate between correctly and incorrectly paired nucleotides.
Detailed explanation-2: -Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell. The replication process relies on the fact that each strand of DNA can serve as a template for duplication.
Detailed explanation-3: -Hydrogen bonds ensure the faithfulness of DNA replication. This is because they ensure that the correct base is incorporated by the enzyme DNA polymerase.
Detailed explanation-4: -DNA replication requires other enzymes in addition to DNA polymerase, including DNA primase, DNA helicase, DNA ligase, and topoisomerase.
