What is this?
A chromosome is like a super-organized package that holds all your DNA, which is the instruction manual for your body. These packages help make sure your DNA is copied correctly when your cells divide and grow.
Key Parts to Explore
DNA
This is the special molecule that carries all the instructions for building and operating your body.
Histones
These are tiny proteins that act like spools, helping to neatly wind and pack the long DNA strands into a compact shape.
Chromatid
This is one of the two identical copies of a chromosome that are joined together before a cell divides.
Centromere
This is the special spot in the middle of a chromosome that holds the two identical chromatids together.
Did You Know?
If you stretched out all the DNA from just one of your cells, it would be about 2 meters long, but it all fits inside a tiny chromosome!
