An electron micrograph of a prokaryote (Escherichia coli), showing DNA and ribosomes
This Escherichia coli cell has been treated with chemicals and sectioned so its DNA and ribosomes are clearly visible. The DNA appears as swirls in the center of the cell, and the ribosomes appear as dark particles at the cell periphery.
