ADA is an enzyme which is deficient in a genetic disorder SCID. What is the full form of ADA?

Options

A. Adenosine Deoxy Aminase
B. Adenosine Deaminase
C. Aspartate Deaminase
D. Arginine Deaminase

Answer

To answer the question regarding the full form of ADA, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Context**: The question mentions ADA in relation to a genetic disorder called SCID. Understanding the context helps narrow down what ADA refers to.

2. **Recall the Options**: The options given are:
- Adenosine deoxyaminase
- Adenosine deaminase
- Aspirin deaminase
- Arginine deaminase

3. **Analyze the Options**:
- Adenosine deoxyaminase is not commonly associated with SCID.
- Aspirin deaminase and Arginine deaminase are not relevant in the context of the immune system or SCID.
- Adenosine deaminase is known to play a crucial role in the immune system.

4. **Confirm the Correct Answer**: Based on the knowledge that ADA is associated with the maintenance of the immune system and is deficient in SCID, we can conclude that the correct full form of ADA is **Adenosine deaminase**.

5. **Final Answer**: The full form of ADA is **Adenosine deaminase**.
