To address the question, let’s break down each option:
- A. Error rates for DNA replication are reduced by proofreading the DNA polymerase: This statement is true. DNA polymerases have a proofreading ability that allows them to correct errors during DNA synthesis, significantly lowering the error rate.
- B. Replication forks represent areas of active DNA synthesis on the chromosomes: This statement is also true. Replication forks are indeed the sites where the DNA double helix is unwound, and new strands are synthesized, making them critical for DNA replication.
- C. Ligases and polymerases: This statement is incomplete and likely false as it stands. DNA ligase is responsible for joining Okazaki fragments on the lagging strand, while DNA polymerases synthesize new DNA strands. The statement lacks clarity about their roles and thus can be considered misleading.
Therefore, the false statement among the options is C, as it does not provide accurate or complete information regarding the roles of ligases and polymerases in DNA replication.
