Where are foreign DNA and plasmids put together to form recombinant plasmids?
Question:
Where are foreign DNA and plasmids put together to form recombinant plasmids?
Recombinant DNA technology:
Recombinant DNA technology is an emerging field in which the DNA can be transferred from one cell to another in the laboratory. This new technique helps alter the genome of an organism and can also be used to modify the diseased or mutated genes
