Answer:
The correct answer is option D, Bacteria Make Human Insulin
Step-by-step explanation:
Through the recombinant technology of genetic engineering, DNA of one organism can be transferred into the DNA of other organism. In a bacteria, the genes can be modified to produce human insulin. The gene for human insulin is chemically joined to the plasmid of bacterial DNA. Thus whenever the bacteria replicates its DNA, it also replicates the gene for human insulin thereby producing multiple sets of synthetic human insulin.
