Question

In which of the following was genetic engineering first employed commercially?

• A. To develop human DNA using bacteria.
• B. To develop genetically modified plants with high resistance.
• C. To develop human insulin using bacteria.
• D. To develop genetically modified plants with high productivity.

Answer 1

The correct option is C

To develop human insulin using bacteria.

Genetic engineering technology was first employed to manufacture human insulin from bacteria. The gene responsible for the production of human insulin was inserted into the bacteria and as a result, it produced inactive form of insulin. Later, it was converted into active form.
