  • Two segments of chromatin are shown. Each is made up of eight yellow balls (laid out in a four-by-two pattern) that represent histones and a colorful thread, representing DNA, that goes around the histones; collectively, these are the nucleosomes . The top chromatin has the nucleosomes more spread out than the bottom chromatin. Gene expression on the top chromatin is represented by a green protein that is shooting out segments of RNA. There is no gene expression on the bottom chromatin: the nucleosomes are tightly packed in a line and the DNA has a smattering of red spots throughout, representing methyl groups.
