WebChromosomes are structures that look like thread, which live in the nucleus (center) of cells. One molecule of DNA and one protein make up one chromosome. Chromosomes are different sizes, and proteins called histones allow them to pack up small enough to fit in a nucleus. Without these, our chromosomes would be as tall as we are! WebChromosomes are found in the pairs, in the nucleus. You gain one chromosome from each parent, a maternal and paternal gene. What is required to happen before mitosis? …
