DNA's Cozy Home. Your DNA is so incredibly long that it would stretch across your room if it were unwound, but it fits inside your cells because it wraps tightly around special proteins called histones, like thread wound around a spool.
Instructions Inside. Chromosomes are like instruction manuals for your body, containing genes that tell your cells how to make proteins and do their jobs.
Humans Have 46. You have 46 chromosomes in most of your cells, arranged in 23 pairs, and you get one from each parent.
Super Organized. The DNA and proteins in a chromosome create a complicated 3D structure that helps cells read which genes should be turned on or off at just the right time.
