The centriole pair occurs in a complex called

Options

A. Centrosome
B. Centromere
C. Kinetochore
D. Basal plate

Answer

To answer the question, "The centriole pair occurs in a complex called," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Centrioles**:
- Centrioles are cylindrical structures made up of protein tubulin. They usually occur in pairs and are oriented at right angles to each other.

2. **Identify the Complex that Contains Centrioles**:
- The two centrioles together form a structure known as the centrosome. The centrosome is a key component of the cell's cytoskeleton.

3. **Discuss the Function of the Centrosome**:
- The centrosome plays a crucial role in organizing microtubules, which are essential for various cellular processes, including cell division. During mitosis, the centrosome helps in pulling apart chromatids.

4. **Evaluate the Options Provided**:
- **Centrosome**: This is the correct answer as it is the complex that contains the centriole pair.
- **Centromere**: Incorrect, as this refers to a region on a chromosome.
- **Kinetochore**: Incorrect, as this is a structure where spindle fibers attach to chromosomes during cell division.
- **Basal Plate**: Incorrect, as this term does not relate to centrioles.

5. **Conclude the Correct Answer**:
- Based on the analysis, the centriole pair occurs in a complex called the **centrosome**.

### Final Answer:
The centriole pair occurs in a complex called **centrosome**.
