Answer:
The correct answer is option D, recombinant DNA
Step-by-step explanation:
Recombinant DNA is produced by combining the DNA strands from two or more species to produce an indistinctive genome from multiple source. For example – Human insulin recombinant DNA is produced by taking out the insulin coding gene from the human pancreas and combining it with the plasmid DNA of bacteria. This recombinant DNA containing human insulin is then again inserted into the bacteria to produce several copies of it.
