Detailed explanation-1: -Bacteriophages, also known as phages, are viruses that infect and replicate only in bacterial cells. They are ubiquitous in the environment and are recognized as the most abundant biological agent on earth.

Detailed explanation-2: -A bacteriophage (/bækˈtɪərioʊfeɪdʒ/), also known informally as a phage (/ˈfeɪdʒ/), is a duplodnaviria virus that infects and replicates within bacteria and archaea. The term was derived from “bacteria” and the Greek (phagein), meaning “to devour".

Detailed explanation-3: -To infect bacteria, most bacteriophages employ a ‘tail’ that stabs and pierces the bacterium’s membrane to allow the virus’s genetic material to pass through. The most sophisticated tails consist of a contractile sheath surrounding a tube akin to a stretched coil spring at the nanoscale.

Detailed explanation-4: -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-5: -The N gene protein, pN, of bacteriophage stimulates early gene transcription by allowing mRNA chain elongation to proceed into genes distal to transcription termination sites normally recognized by the Escherichia coli transcription termination protein .
