Which type of chemical mutagen is incorporated into the genome by DNA polymerase during replication?
This outcome reflects nucleic acid structure and recombination, where hairpin formation, Holliday junction resolution and translation control ensure fidelity. Option B captures this correctly because it matches molecular mechanisms, consistent with textbook descriptions and experimental observations in molecular biology.
Ref: Alberts et al., Molecular Biology of the Cell, 6th Edition, Chapter 5, DNA Replication and Repair, discusses Holliday junction formation during homologous recombination and replication fork dynamics ensuring genome duplication.
