NEET BIOLOGY

Detailed explanation-1: -A bacteriophage is a type of virus that infects bacteria. In fact, the word “bacteriophage” literally means “bacteria eater, ” because bacteriophages destroy their host cells. All bacteriophages are composed of a nucleic acid molecule that is surrounded by a protein structure.

Detailed explanation-2: -More common, but less understood, are cases of viruses infecting bacteria known as bacteriophages, or phages.

Detailed explanation-3: -A bacteriophage (/bækˈtɪərioʊfeɪdʒ/), also known informally as a phage (/ˈfeɪdʒ/), is a duplodnaviria virus that infects and replicates within bacteria and archaea.

Detailed explanation-4: -The phage infection cycle seems to be simple but extremely efficient: a single phage injects its genome into a bacterial cell, switching the cells’ programme in its favour so the host cell will eventually die and release about 100 new phage particles.
