If the centromere is terminal , the chromosome is

Options

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

Answer

To solve the question "If the centromere is terminal, the chromosome is?", we need to understand the different types of chromosomes based on the position of the centromere.

### Step-by-Step Solution:

1. **Understand the Centromere**: The centromere is the constricted region of a chromosome where the sister chromatids are joined. Its position can vary, leading to different classifications of chromosomes.

2. **Identify Chromosome Types**:
- **Metacentric Chromosomes**: These have the centromere located at the center, resulting in two arms of equal length.
- **Submetacentric Chromosomes**: These have the centromere slightly off-center, leading to one arm being slightly longer than the other.
- **Telocentric Chromosomes**: These have the centromere located at one end (terminal), resulting in one arm being very short or absent.
- **Acrocentric Chromosomes**: These have the centromere located near one end, resulting in one long arm and one very short arm.

3. **Analyze the Question**: The question specifies that the centromere is terminal. This means it is located at one end of the chromosome.

4. **Determine the Correct Answer**: Since the centromere is at the terminal position, the type of chromosome that fits this description is the **telocentric chromosome**.

5. **Conclusion**: Therefore, the correct answer to the question is **telocentric**.

### Final Answer:
The chromosome is **telocentric**.
