Find the CORRECT match from the following .

Options

A. Cry I Ab - Cotton bollworms
B. RNAi - Meloidegyne incognita
C. First transgenic cow- Dolly
D. Eli Lilly and company - Gene therapy

Answer

To solve the question of finding the correct match from the provided options, we will analyze each statement step-by-step.

### Step-by-Step Solution:

1. **Analyzing the first option:**
- The gene Cry1ab is mentioned to control the cotton ball worm.
- However, Cry1ab is actually a gene that controls the corn borer, not the cotton ball worm.
- Therefore, this option is incorrect.

**Hint:** Check the specific pest each Cry gene targets to determine correctness.

2. **Analyzing the second option:**
- RNA interference (RNAi) is said to have been done in Meloidogyne incognita.
- Meloidogyne incognita is a nematode that causes infections in plants, including tobacco.
- RNA interference is indeed a technique used to make plants pest-resistant.
- This option is correct.

**Hint:** Consider the role of RNA interference in pest resistance and its application in plant pathology.

3. **Analyzing the third option:**
- It states that Dolly is the first transgenic cow.
- However, Dolly was the first cloned sheep, not a cow.
- The first transgenic cow is Rosie, who was created in 1997 and produced human alpha-lactalbumin.
- Thus, this option is incorrect.

**Hint:** Remember the distinction between cloning and transgenic animals.

4. **Analyzing the fourth option:**
- It claims that L.A. Lilly introduced gene therapy.
- In reality, L.A. Lilly is known for introducing human insulin (Humulin), not gene therapy.
- Therefore, this option is also incorrect.

**Hint:** Identify the key contributions of companies in biotechnology to verify statements.

### Conclusion:
After analyzing all the options, the only correct match is the second option regarding RNA interference in Meloidogyne incognita.

### Final Answer:
The correct match is option 2: RNA interference was done in Meloidogyne incognita.
