T4 bacteriophage. Negatively stained transmission electron micrograph (TEM) of a T4 bacteriophage virus particle. A bacteriophage is a virus that infects bacteria. It consists of an icosahedral (20-sided) head (lower right),which contains the genetic material,a tail (cylinder) and tail fibres (leg-like),which fix it to a specific receptor site. Once attached to a bacterium,the bacteriophage injects its DNA and the bacterium's cellular mechanisms are used to produce more bacteriophages. The T4 bacteriophage infects Escherichia coli (E. coli) bacteria | |
