At which place are the chromosome attached to the spindle fibres?

Explanation

**Step-by-Step Solution:**

1. **Understanding the Context**: The question asks where chromosomes attach to spindle fibers during cell division. This occurs during a specific phase of the cell cycle.

2. **Identifying the Phase**: The attachment of chromosomes to spindle fibers happens during the metaphase of cell division. During metaphase, chromosomes are aligned at the equatorial plane of the cell.

3. **Structure of Chromosomes**: Each chromosome consists of two identical halves called chromatids, which are joined together at a region known as the centromere.
