Recombinant DNA Bacterial cells protect their own DNA from degradation by restriction endonucleases by not producing any restriction endonucleases deleting all recognition sites from the genome having anti restriction endonucleases methylating the DNA at the sites that the enzyme recognizes not producing any restriction endonucleases deleting all recognition sites from the genome having anti restriction endonucleases methylating the DNA at the sites that the enzyme recognizes ANSWER DOWNLOAD EXAMIANS APP
