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 methylating the DNA at the sites that the enzyme recognizes having anti restriction endonucleases not producing any restriction endonucleases deleting all recognition sites from the genome methylating the DNA at the sites that the enzyme recognizes having anti restriction endonucleases ANSWER DOWNLOAD EXAMIANS APP
