In humans, MHC proteins are encoded by genes present on

Options

A. Chromosome 5
B. Chromosome 6
C. Chromosome 7
D. Chromosome 9

Answer

To solve the question regarding the encoding of MHC proteins in humans, we can follow these steps:

### Step-by-Step Solution:

1. **Understand MHC Proteins**: MHC (Major Histocompatibility Complex) proteins are crucial for the immune system as they help T cells distinguish between self and non-self cells.

2. **Identify the Chromosome**: MHC proteins are encoded by specific genes located on a particular chromosome.

3. **Examine the Options**: The question provides four options regarding the chromosomes:
- Option A: Chromosome 5
- Option B: Chromosome 6
- Option C: Chromosome 7
- Option D: Chromosome 9

4. **Evaluate Each Option**:
- **Chromosome 5**: This is incorrect as MHC genes are not located here.
- **Chromosome 6**: This is correct. The MHC genes are indeed located on chromosome 6.
- **Chromosome 7**: This is incorrect as MHC genes are not found on this chromosome.
- **Chromosome 9**: This is also incorrect as MHC genes do not reside here.

5. **Conclude the Answer**: Based on the evaluation, the correct answer is **Chromosome 6**.

### Final Answer:
MHC proteins in humans are encoded by genes present on **Chromosome 6**.
