Mark the incorrect pair

Options

A. Bt cotton - Genes from Agrobacterium
B. SCID - ADA defucuebcy
C. Rosie - a lactalbumin
D. Ely-lily-Humulin

Answer

To solve the question of identifying the incorrect pair, we will analyze each option provided in the question step by step.

### Step 1: Analyze the first option - BT cotton, genes from agrobacterium
- **Explanation**: BT cotton is genetically modified to express a toxin from the bacterium *Bacillus thuringiensis*, which makes it resistant to certain pests. The genes used for BT cotton are not derived from *Agrobacterium*, but rather from *Bacillus thuringiensis*.
- **Conclusion**: This pair is incorrect.

### Step 2: Analyze the second option - SCID, ADA deficiency
- **Explanation**: Severe Combined Immunodeficiency (SCID) is a genetic disorder caused by a deficiency in the enzyme adenosine deaminase (ADA). This pair correctly identifies the cause of SCID.
- **Conclusion**: This pair is correct.

### Step 3: Analyze the third option - Rosy alpha-lactoalbumin
- **Explanation**: Rosy was a transgenic cow that produced milk enriched with human alpha-lactalbumin. This milk was designed to be more nutritionally balanced for human infants compared to regular cow milk. Therefore, this pair is also correct.
- **Conclusion**: This pair is correct.

### Step 4: Analyze the fourth option - Eli Lilly, Humulin
- **Explanation**: Eli Lilly is known for producing Humulin, which is human insulin made by inserting the genes for insulin into *E. coli* bacteria. This process was indeed carried out in the early 1980s, making this pair correct as well.
- **Conclusion**: This pair is correct.

### Final Conclusion:
After analyzing all the options, the only incorrect pair is **BT cotton, genes from agrobacterium**.

### Summary of the Solution:
- The incorrect pair is **BT cotton, genes from agrobacterium** because BT cotton uses genes from *Bacillus thuringiensis*, not *Agrobacterium*.
