In Ell Lily"s method of inulin production , which of the following is correct ?

Options

A. A peptide and B peptide were produced from the same host cell
B. A peptide and B peptide were produced from different host cells.
C. A peptide and B peptide C peptide were produced from the same host cell
D. A peptide and B peptide C peptide were produced from different host cell s.

Answer

To solve the question regarding L. Lilly's method of insulin production, we need to analyze the information provided in the video transcript step by step.

### Step-by-Step Solution:

1. **Understanding L. Lilly's Method**: L. Lilly is an American company known for producing insulin. The method involves extracting insulin from human sources.

2. **Extraction of Peptides**: In this method, two different peptides, referred to as A peptide and B peptide, are extracted from two different human sources. This means that A peptide comes from one human (let's call them Human A) and B peptide comes from another human (Human B).

3. **Recombination in E. coli**: The extracted genes for A peptide and B peptide are then recombined in a plasmid of E. coli. This allows for the mass production of insulin, which is sold as artificial insulin.

4. **Evaluating the Options**:
- **Option A**: "A peptide and B peptide were produced from the same host cell." - This is incorrect because they were extracted from different humans.
- **Option B**: "A peptide and B peptide were produced from different hosts." - This is correct, as they were derived from different human sources.
- **Option C**: "A peptide and B peptide, C peptide were produced from the same host." - This is incorrect because C peptide is not included in the artificial insulin produced.
- **Option D**: "A peptide and B peptide, C peptide were produced from different hosts." - This is also incorrect because C peptide is not produced in the recombination process.

5. **Conclusion**: The correct answer is **Option B**, as it accurately states that A peptide and B peptide were produced from different hosts.
