Bacteriophage. A bacteriophage is constituted of a protein envelope (called capsid), containing its nucleic acid (DNA or RNA), and a tail. The tail includes a collar (covered with contractile proteins for the most elaborated bacteriophages, such as the T2 and T4 phages) and ending by tail fibres enabling it to attach to the bacteria it infects. | |
