The chromosomes having centromere at terminal end are called

Options

A. sub-metacentric
B. Metacentic
C. Telocentric
D. Acrocentric

Answer

To answer the question regarding the type of chromosome that has its centromere at the terminal end, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Chromosome Structure**:
- Chromosomes are structures within cells that contain DNA. They are made up of chromatin and are visible during cell division, particularly in the metaphase stage.

2. **Identifying the Centromere**:
- The centromere is a constricted region of the chromosome that plays a crucial role during cell division. It is the point where the two sister chromatids are joined.

3. **Types of Chromosomes Based on Centromere Position**:
- Chromosomes can be classified based on the position of the centromere:
- **Metacentric**: Centromere is located at the center, resulting in two equal arms.
- **Submetacentric**: Centromere is slightly off-center, creating one arm longer than the other.
- **Acrocentric**: Centromere is near one end, resulting in one very short arm and one long arm.
- **Telocentric**: Centromere is located at the terminal end of the chromosome.

4. **Conclusion**:
- Since the question specifically asks for chromosomes with the centromere at the terminal end, the correct answer is **telocentric chromosomes**.

### Final Answer:
The chromosomes having the centromere at the terminal end are called **telocentric chromosomes**.
