What are spindle fibres that connect the centromere to respective poles called

Options

A. Astral rays
B. Interphase fibres
C. Chromosomal fibres
D. Interchromosomal fibres

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question asks for the specific name of spindle fibers that connect the centromere of chromosomes to the respective poles during cell division.

2. **Identifying Key Terms**:
- **Spindle Fibers**: These are structures that form during cell division to help separate chromosomes.
- **Centromere**: This is the region of a chromosome where the two sister chromatids are joined together.

3. **Analyzing the Options**:
- **Estural Rays**: These are not related to spindle fibers.
- **Interface Fibres**: These do not form during cell division; they are associated with the interphase of the cell cycle.
- **Chromosomal Fibres**: This term refers to the spindle fibers that attach to the centromere during cell division.
- **Interchromosomal Fibres**: These are not specifically related to the attachment of spindle fibers to centromeres.

4. **Conclusion**: The correct answer is **Chromosomal Fibres**. These fibers connect the centromere of the chromosomes to the spindle poles during the process of cell division.

5. **Final Answer**: The spindle fibers that connect the centromere to respective poles are called **Chromosomal Fibres**.
