Two plasmids are of the same compatibility group if they
nucleic acid structure and recombination analysis shows hairpin formation, Holliday junction resolution and translation control ensure fidelity. Consequently cannot co-exist in the same bacterial cell emerges as the valid choice since it matches molecular mechanisms, aligning with established principles in molecular biology literature.
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.
