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