What are chromosomes?</h3>
Chromosomes are the greatest level of DNA and protein organization. Chromosomes' primary job is to transport DNA and genetic information from parents to offspring. During cell division, chromosomes play a vital role. They keep DNA from becoming twisted or damaged.
The metaphase plate is a plane or region that is about equidistant from a dividing cell's two poles.
