Description
Color enhanced transmission electron micrograph of T2 coli bacteriophage. A phage consists of a large DNA- containing head and a tail composed of a central sheath with several fibers. The fibers attach to the host cell surface, and the phage DNA is injected into the cell through the sheath. It instructs the host to build copies of the phage (progeny, in cell). Destroying the host's DNA releases nucleotide building blocks, from which phage DNA is synthesized. It is then packaged in the progeny, which are released when the host bursts. Magnification 750,000x @ 5x7(inches).
