Here's a breakdown:
* DNA: Deoxyribonucleic acid, the molecule that carries the genetic instructions for an organism.
* Chromosomes: Long, thread-like structures made up of DNA tightly coiled around proteins called histones.
* Nucleus: The control center of the cell, where the chromosomes are located.
So, to put it simply, DNA is organized into chromosomes, and those chromosomes are found within the nucleus of a cell.
