Which of the following statements is/are true about genetically engineered insulin ?
A. Its name is humulin
B. It was manufactured by American firm Eli Lilly
C. It was launched on 5 July 1983
D. It is produced by the fermentation of appropriate recombinant E. coli clones.

Options

A. A, B
B. B, C
C. A, B, C
D. A, B, C, D

Answer

To determine which statements are true about genetically engineered insulin, let's analyze each option step by step:

### Step 1: Analyze Statement A
**Statement A:** Its name is humulin.
**Analysis:** Genetically engineered insulin is indeed known as "Humulin." This statement is true.

### Step 2: Analyze Statement B
**Statement B:** It was manufactured by American firm Eli Lilly.
**Analysis:** Humulin was developed and manufactured by the American pharmaceutical company Eli Lilly. This statement is also true.

### Step 3: Analyze Statement C
**Statement C:** It was launched on 5 July 1983.
**Analysis:** Humulin was indeed launched on July 5, 1983. This statement is true.

### Step 4: Analyze Statement D
**Statement D:** It is produced by the fermentation of appropriate recombinant E. coli clones.
**Analysis:** Genetically engineered insulin is produced using recombinant DNA technology, where the insulin gene is inserted into E. coli bacteria, allowing them to produce insulin through fermentation. This statement is true.

### Conclusion:
All statements A, B, C, and D are true about genetically engineered insulin.

### Final Answer:
**All statements (A, B, C, and D) are true.**
