Chromosomes with unequal length of arms are

Options

A. meta and sub metacentric
B. sub meta and Acrocentric
C. acro and Telocentric
D. submeta, Acro and Telocentric

Answer

To solve the question "Chromosomes with unequal length of arms are?", we will analyze the types of chromosomes based on the position of their centromeres.

### Step-by-Step Solution:

1. **Understanding Chromosome Structure**:
- Chromosomes consist of two arms (the sections of the chromosome on either side of the centromere) and a centromere that holds the two chromatids together.

2. **Types of Chromosomes**:
- **Metacentric Chromosomes**: These have the centromere located in the middle, resulting in two arms of equal length. Therefore, they do not have unequal lengths.
- **Submetacentric Chromosomes**: In these chromosomes, the centromere is slightly off-center, leading to one arm being longer than the other. This means they do have unequal lengths.
- **Acrocentric Chromosomes**: Here, the centromere is located closer to one end of the chromosome, resulting in one very short arm and one very long arm. This also means they have unequal lengths.
- **Telocentric Chromosomes**: In these chromosomes, the centromere is located at the very end, which also results in one arm being significantly longer than the other.

3. **Identifying the Correct Answer**:
- The question asks for chromosomes with unequal lengths of arms. Based on our analysis:
- Submetacentric and acrocentric chromosomes both have unequal lengths of arms.
- Therefore, the correct answer is that chromosomes with unequal lengths of arms are **submetacentric and acrocentric**.

### Conclusion:
The correct answer to the question is that chromosomes with unequal lengths of arms are **submetacentric and acrocentric**.
