"`The two _____A____ together with spindle fibres forms ____B____".
Complete the above statement by chossing the correct option for A and B.

Options

A. Microtubules Mitotic apparatus
B. Asters Mitotic apparatus
C. Microtubules Centriole
D. Asters Centriole

Answer

To complete the statement, we need to identify the correct terms for A and B based on the context of cell division.

1. **Understanding the components involved**:
- During cell division, particularly during mitosis, certain structures are crucial for the separation of chromosomes.
- The centrosome is a key player in this process as it duplicates and moves to opposite poles of the cell.

2. **Identifying A**:
- The term "asters" refers to the star-shaped structures formed by the microtubules that radiate from the centrosomes during cell division.
- Therefore, A should be "asters".

3. **Identifying B**:
- The combination of the asters and spindle fibers (which are also microtubules that help in the movement of chromosomes) forms a structure that is essential for the process of mitosis.
- This structure is known as the "mitotic apparatus", which is responsible for the proper segregation of chromosomes during cell division.
- Thus, B should be "mitotic apparatus".

4. **Final Statement**:
- The completed statement is: "The two **asters** together with spindle fibres forms **mitotic apparatus**."
