In a study, bacterial culture of E. coli was infected with bacteriophage. How- ever, these cultures were protected from phage infection. Interestingly, it was found that the resistance is due to endonudeases present in E. coli, which deaved the phage DNA. How is the E. coli genomic DNA protected from the action of these endonuclease enzymes?
