The chrormosomes in which centromere are situated close to one end are

Options

A. Telocentric
B. Sub-metacentric
C. Metacentric
D. Acrocentrie

Answer

To solve the question regarding the type of chromosomes in which the centromere is situated close to one end, we can analyze the options provided:

1. **Understanding Chromosome Types**:
- **Telocentric**: In telocentric chromosomes, the centromere is located at the very end of the chromosome. This means that there is no arm on one side of the chromosome.
- **Submetacentric**: In submetacentric chromosomes, the centromere is slightly off-center, resulting in one arm being somewhat longer than the other.
- **Metacentric**: In metacentric chromosomes, the centromere is located in the middle, resulting in two arms of equal length.
- **Acrocentric**: In acrocentric chromosomes, the centromere is located closer to one end than the other, resulting in one very short arm and one longer arm.

2. **Analyzing the Options**:
- **Option A (Telocentric)**: The centromere is at the end, not just close to one end. This is incorrect.
- **Option B (Submetacentric)**: The centromere is near the center, not close to one end. This is incorrect.
- **Option C (Metacentric)**: The centromere is in the middle, which does not fit the description. This is incorrect.
- **Option D (Acrocentric)**: The centromere is indeed located close to one end, which matches the question's requirement.

3. **Conclusion**:
- The correct answer is **D. Acrocentric**, as the centromere is situated close to one end of the chromosome.
