The chromosomes in which centromere is situated close to end are

Options

A. metacentric
B. acrocentric
C. telocentric
D. submetacentric

Answer

To determine the type of chromosome where the centromere is situated close to one end, we can analyze the different types of chromosomes based on the position of the centromere. Here’s a step-by-step breakdown:

### Step-by-Step Solution:

1. **Understanding Chromosome Types**:
- Chromosomes can be classified based on the position of the centromere. The main types are:
- **Metacentric**: The centromere is located in the middle, resulting in two arms of equal length.
- **Sub-metacentric**: The centromere is slightly off-center, leading to one arm being longer than the other.
- **Acrocentric**: The centromere is located closer to one end, resulting in one very short arm and one long arm.
- **Telocentric**: The centromere is located at the terminal end of the chromosome.

2. **Identifying the Correct Type**:
- The question specifies that we need to find the chromosome type where the centromere is situated close to one end.
- From the definitions above, the **acrocentric** chromosome fits this description as the centromere is near one end.

3. **Conclusion**:
- Therefore, the correct answer to the question is **acrocentric** chromosomes.

### Final Answer:
The chromosomes in which the centromere is situated close to one end are **acrocentric**.
