Solution

Metaphase:
The chromosomes are positioned at the cell's equatorial plate during metaphase.
The centromere of each chromosome attaches itself to a spindle fiber.
Chromosomes:
Chromosomes are threadlike structures made up of protein and a single molecule of DNA that carry genetic information from one cell to the next.
Centromere
A centromere is a location on a chromosome where the two chromatids of each chromosome are joined.
Spindle fibers
Spindle fibers are a type of protein that divides a cell's genetic material.
