Question

Describe the structure and reproduction of bacteriophage

Answer 1

The virion of T-even phage is binal or tadpole like structure with a polyhedral head connected to a helical tail through a short collar. The head composed of about 2000 capsomeres arid encloses a tightly packed dsDNA (50 nm long). The tail has an inner hollow tube called core, surrounded by a contractile sheath which consists of 24 annular rings. The distal end of the tube is connected to a hexagonal basal plate with spike or tail spin at each corner. Six long, flexible tail fibers also arise from the basal plate which helps in adsorption to bacteria 

The whole process involves following steps:

(a) Adsorption or infection

(d) Virion assembly

(b) Penetration or injection

(e) Lysis or release

(c) Synthesis of phage components
