Why is genetically produced insulin better than those produced by conventional methods?

Explanation

### Step-by-Step Solution:

1. **Understanding Insulin Production**: Insulin is a hormone crucial for regulating blood sugar levels, and it is primarily used in the treatment of diabetes. There are two main methods for producing insulin: conventional methods and genetically engineered methods.

2. **Conventional Method of Insulin Production**: In the conventional method, insulin is extracted from the pancreases of slaughtered animals, primarily pigs and cattle. This process involves harvesting the insulin from these animal sources.

3. **Issues with Conventional Insulin**: The insulin obtained from animal sources can lead to allergic reactions in some patients. This is because the insulin derived from pigs or cattle is a foreign protein to the human body, which may trigger an immune response.
