Recombinant DNA Charged molecules are separated based on varying rates of migration through a solid matrix when subjected to an electric field. This technique is known as autoradiography blotting photoreactivation gel electrophoresis autoradiography blotting photoreactivation gel electrophoresis ANSWER DOWNLOAD EXAMIANS APP
Recombinant DNA Vectors are molecules that are able to covalently bond to and carry foreign DNA into cells molecules that help in replication molecules that protect host cells from invasion by foreign DNA molecules that degrade nucleic acids molecules that are able to covalently bond to and carry foreign DNA into cells molecules that help in replication molecules that protect host cells from invasion by foreign DNA molecules that degrade nucleic acids ANSWER DOWNLOAD EXAMIANS APP
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
