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 solve the question regarding the full form of ADA in the context of the genetic disorder SCID, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Context**: The question mentions ADA in relation to SCID, which is a genetic disorder. Understanding the relationship between these terms is crucial.

2. **Understand SCID**: SCID stands for Severe Combined Immunodeficiency Syndrome. It is a condition characterized by a significant defect in the immune system, leading to a lack of functional T lymphocytes.

3. **Link ADA to SCID**: The deficiency of ADA (Adenosine Deaminase) is one of the causes of SCID. In individuals with SCID, the lack of this enzyme leads to the accumulation of toxic metabolites that are harmful to lymphocytes.

4. **Define ADA**: ADA is an enzyme that plays a vital role in the purine salvage pathway, which is crucial for the proper functioning of the immune system.

5. **Conclusion**: Therefore, the full form of ADA is **Adenosine Deaminase**.

### Final Answer:
The full form of ADA is **Adenosine Deaminase**.
