Question

Bacteriophage virus is the--; 1) Bacterial virus; 2) Fungal Virus; 3) Algal virus; 4) Protozoal virus

Answer 1

$\underline{\underline{\sf Bacteriophage - }}$

• Virus infected bacteria are known as Bacteriophages.

• A typical bacteriophage consists of a polyhedral head, collar piece, neck and six tail fibers.

• The tail ranging from end of neck to the tail fibers is covered by a sheath.

• Bacteriophages generally have a double stranded circular or linear DNA housed in the head.

• The nucleic acids are protected by a proteinaceous covering called capsid.

• On the basis of reproduction, there are two kinds of bacteriophage - Phagic Bacteriophage & Pinocytic Bacteriophage.

• In a Phagic Bacteriophage, only the genetic material enters the host organism while the whole of pinocytic bacteriophage enters the host organism except the envelope.

Example, T-4 Bacteriophage
