The region of a chromosome to which the microtubules of the spindle attach during cell division is called the centromere.

Here are the steps of how this attachment occurs:

1. During the phase of cell division known as prophase, the chromosomes condense and become visible. Each chromosome has two sister chromatids, which are joined at a region called the centromere.

2. As the cell enters metaphase, the microtubules of the spindle apparatus attach to the chromosomes at the centromere. This is facilitated by a structure called the kinetochore, which is located at the centromere and serves as the attachment point for the spindle microtubules.

3. The spindle microtubules then help align the chromosomes at the cell's equator, or metaphase plate.

4. During anaphase, the sister chromatids separate, and the now individual chromosomes move to opposite ends of the cell. The spindle microtubules shorten, pulling the chromosomes toward the poles of the cell.

5. Finally, during telophase, the chromosomes reach the poles and begin to decondense, and the cell divides.

So, in summary, the centromere is the region of the chromosome where the spindle microtubules attach during cell division.
