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