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