Question

a patient with diabetes begins using insulin produced through recombinant dna technology instead of insulin extracted from animals. which statement best explains the main individual benefit of this choice?

it increases the patient’s genetic diversity, making them less susceptible to other diseases.

it provides insulin that is chemically identical to human insulin, reducing allergic reactions and improving treatment effectiveness.

it guarantees that the patient will never need insulin again.

it allows the patient to produce their own insulin without medical assistance.

Explanation:

• Analyze Option 1: Recombinant DNA insulin does not affect a patient's genetic diversity, so this is incorrect.
• Analyze Option 2: Recombinant insulin is chemically identical to human insulin. Animal - derived insulin may cause allergic reactions due to differences from human insulin. So this option explains the benefit correctly.
• Analyze Option 3: Diabetes is a chronic condition, and recombinant insulin does not cure diabetes, so the patient will still need insulin. This is incorrect.
• Analyze Option 4: Recombinant insulin is administered externally; it does not make the patient produce their own insulin without medical help. This is incorrect.

Answer:

B. It provides insulin that is chemically identical to human insulin, reducing allergic reactions and improving treatment effectiveness.
