Cell nucleus. Coloured scanning electron micrograph (SEM) of a section through the nucleus (centre right) of a kidney cell. The cell nucleus contains the cell's genetic information in the form of DNA (deoxyribonucleic acid). Here the DNA is complexed with proteins to form chromatin (light brown structures). Surrounding the nucleus are mitochondria (ovoids), which supply the cell with energy.
