A Bacteriophage

Caption

Bacteriophages come in different shapes and sizes. This one has a "head" containing the virus' DNA and a "tail" with which it attaches to bacterial cells when it infects them. The scale bar in this electron microscope image is about one thousandth the diameter of a human hair.
