WebThese findings ultimately led to the proposal of a restriction-modification (R-M) system, in which a restriction enzyme and a methylase from the host work together to cleave foreign viral (non-methylated) DNA while keeping the host DNA protected through methylation [6]. WebIt is concluded that host specificity is carried on the bacteriophage DNA. Phage P1, present in a bacterial cell as either prophage or vegetative phage, imparts to λ DNA multiplying in the same cell a host specificity over and above that determined by the host itself.
