Round And Round It Wrapped......

a: Chromatin ~
b: baseballs wrapped in a spaghetti

What: Chromatin is a combination of protein and DNA that occurs in the Eukaryotic nucleus. The ball portion in this analogy is the protein portion which is made of positively charge amino acids that bind to the negative charges of the DNA spaghetti. The DNA is wrapped around the protein which enables a very long piece of DNA to be stored in a very small space.
