Certain bacteria can be made to produce marketable levels of a protein product such as insulin. How is this process accomplished?
A. The protein product is injected into bacterial cells; as the bacteria reproduce, they produce more of the protein product.
B. The protein product is included in the culture medium of the bacterial cells; as the bacteria divide, they incorporate the protein product from the medium and produce more of it.
C. The gene for the protein product is inserted into a plasmid of the bacterial cells; as the bacteria reproduce, they produce more of the protein product.
D. The gene for the protein product is inserted into the nucleus of the bacterial cells; as the bacteria divide, they produce more of the protein product.

C. The gene for the protein product is inserted into a plasmid of the bacterial cells; as the bacteria reproduce, they produce more of the protein product.

Explanation:

Recombinant technology itself is the process where specific bacteria are made to secrete marketable quantities of the attached protein product like insulin, and this process entails cloning the gene of the protein product into the plasmid of bacterial cells. This is carried out through a process known as transformation where the plasmid, with the wanted gene, is inserted into the bacteria cells. The bacteria then incorporate the plasmid and partly exhibit the gene and this results in synthesis of the proteins.

Therefore, the correct answer option is C.
