Explanation

### Step-by-Step Solution for the Production of Genetically Engineered Insulin

1. **Understanding Insulin Structure**:
- Natural insulin consists of two polypeptide chains, known as Chain A and Chain B, which are linked by disulfide bonds.

2. **Preparation of DNA Sequences**:
- The first step involves synthesizing two specific DNA sequences that correspond to the amino acid sequences of Chain A and Chain B of human insulin.
