Which statement best describes human insulin that is produced by genetically engineered bacteria?

1. This insulin will not function normally in humans because it is produced by bacteria.
2. This insulin is produced as a result of human insulin genes being inserted into bacterial cells.
3. This insulin is produced as a result of exposing bacterial cells to radiation, which produces a mutation.
4. This insulin may have fewer side effects than the insulin previously extracted from the pancreas of other animals.

Genetically engineered bacteria produce human insulin that is chemically identical to naturally produced insulin, reducing immune responses in diabetic patients.

Explanation:

Human insulin produced by genetically engineered bacteria, such as E. coli, is chemically identical to naturally produced insulin. The insulin gene is inserted into the bacteria's DNA, allowing for the mass production of human insulin.

Genetic engineering enables the production of insulin that closely resembles human insulin, reducing the risk of immune responses in diabetic patients.

Recombinant insulin production in bacteria provides a safer and more efficient alternative to insulin sourced from animals. This method enables the production of large quantities of insulin for medical use.
