A chromosome with centromere near the middle is called

Options

A. Metacentric
B. Submetacentric
C. Acrocentric
D. Telocentric

Answer

To solve the question "A chromosome with centromere near the middle is called," we will follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Chromosomes**:
- Chromosomes are structures within cells that contain DNA. They are made up of two sister chromatids joined at a point called the centromere.

2. **Identify the Types of Chromosomes Based on Centromere Position**:
- Chromosomes can be classified based on the position of the centromere into four main types:
- **Metacentric**: Centromere is located near the middle, resulting in two equal arms.
- **Submetacentric**: Centromere is slightly off-center, resulting in one arm being longer than the other.
- **Acrocentric**: Centromere is located closer to one end, resulting in one very short arm and one very long arm.
- **Telocentric**: Centromere is located at the very end of the chromosome, resulting in one arm.

3. **Analyze the Question**:
- The question specifically asks for a chromosome with the centromere near the middle.

4. **Select the Correct Answer**:
- Based on the definitions provided, the type of chromosome where the centromere is located near the middle is called **Metacentric**.

5. **Conclusion**:
- Therefore, the answer to the question is **Metacentric**.

### Final Answer:
A chromosome with the centromere near the middle is called **Metacentric**.
