Image: T2 Bacteriophages Attacking E. coli [Colorized TEM] by Lee D. Simon

Lee. D. Simon Coloured transmission electron micrograph (TEM) of T2 bacteriophage viruses (orange) attacking an Escherichia coli bacterium. Each phage consists of a large DNA-containing head and a tail composed of a central sheath with several fibres. The fibres attach to the host cell surface, and the phage DNA is injected into the cell through … Continue reading Image: T2 Bacteriophages Attacking E. coli [Colorized TEM] by Lee D. Simon
