The following are some of the genes and DNA sequences important for Agrobacterium-mediated transformation of plants: i.
This outcome reflects nucleic acid structure and recombination, where hairpin formation, Holliday junction resolution and translation control ensure fidelity. Option A 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.
