Telocentric chromosome differs from acrocentric chromosome in that

Options

A. The former has a subterminal centromere whereas the later has a centrally located centrosome
B. The centromere in the former is terminal and in the later is subterminal
C. The former has a terminal centromere and the later has a medially located centromere
D. None of the above

Explanation

To answer the question regarding the differences between telocentric and acrocentric chromosomes, we can break down the solution into clear steps:

### Step-by-Step Solution:

1. **Definition of Telocentric Chromosome**:
- A telocentric chromosome is characterized by having its centromere located at one end of the chromosome. This results in one long arm and one very short arm.

2. **Definition of Acrocentric Chromosome**:
- An acrocentric chromosome has its centromere positioned slightly off-center, creating one long arm and one short arm. The short arm is still present but is longer than that of a telocentric chromosome.

3. **Comparison of Centromere Position**:
- In telocentric chromosomes, the centromere is terminal, meaning it is located at the very end of the chromosome.
- In acrocentric chromosomes, the centromere is subterminal, meaning it is located near one end but not at the very end.

4. **Visual Representation**:
- To visualize, you can draw both types of chromosomes. For telocentric, draw a line with a dot at one end (the centromere). For acrocentric, draw a line with a dot slightly off-center.

5. **Conclusion**:
- Therefore, the key difference is that telocentric chromosomes have a terminal centromere, while acrocentric chromosomes have a subterminal centromere.
