Recombinant DNA The advantage of using DNA polymerases from thermophilic organisms in PCR is that the DNA polymerases of these bacteria can withstand the high temperatures needed to denature the DNA strands the DNA polymerases of these bacteria never make mistakes while replicating DNA All of these the DNA polymerases of these bacteria are much faster than those from other organisms the DNA polymerases of these bacteria can withstand the high temperatures needed to denature the DNA strands the DNA polymerases of these bacteria never make mistakes while replicating DNA All of these the DNA polymerases of these bacteria are much faster than those from other organisms ANSWER DOWNLOAD EXAMIANS APP
Recombinant DNA Bacterial cells protect their own DNA from degradation by restriction endonucleases by methylating the DNA at the sites that the enzyme recognizes deleting all recognition sites from the genome having anti restriction endonucleases not producing any restriction endonucleases methylating the DNA at the sites that the enzyme recognizes deleting all recognition sites from the genome having anti restriction endonucleases not producing any restriction endonucleases ANSWER DOWNLOAD EXAMIANS APP
