Insulin that is identical to the human form and produced using recombinant DNA technology is called which type?

• A. Porcine insulin
• B. Recombinant insulin
• C. Human insulin
• D. Bovine insulin

Answer: (C)

The main idea is that insulin produced to be identical to the human molecule using recombinant DNA technology is described as human insulin. Because it matches the exact amino acid sequence of endogenous human insulin, it behaves pharmacologically like the body's own insulin and tends to have fewer immune reactions than animal-derived versions. Porcine and bovine insulins come from animals and differ slightly in sequence, which can lead to immunogenicity and variability. Recombinant methods are used to produce insulin that is chemically indistinguishable from human insulin, so the term that best conveys both its identity and its production method is human insulin. While “recombinant insulin” is accurate in a technical sense, it’s less specific about the molecule’s identity to humans, whereas this product is specifically human insulin produced by recombinant technology.
