Question

The duration of DNA synthesis (S phase) in plant cells is 11h and the DNA is replicated at a rate of 100 bp/s/fork. A plant species has about 3.0x 10 ¹⁰ by DNA is genome. The number of bidirectional forks per genome required for replication will be

Explanation

Understanding DNA replication fidelity reveals polymerase proofreading and origin firing ensure accurate duplication. Therefore Option NAT is correct because it matches high-fidelity synthesis mechanisms, which underpins key processes in molecular biology.
