A plasmid DNA when digested with EcoRI gave a single band of 16 Kb. When the same plasmid was digested with BamHI it gav
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 of gene expression, 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 and stability.
