Digital model of a nucleosome, the fundamental structural unit of chromosomes in the eukaryotic cell nucleus, drawn according to x-ray crystallography data. Cells store their chromosomal DNA as chromatin, a compact, well-organized arrangement of tiny bundles known as nucleosomes. Each nucleosome consists of a core group of histone proteins (orange) wrapped in chromosomal DNA (green).
