• Bacteriophages were discovered independently Twort 1915 in the U.K and Hérelle 1917 in France and the term was coined by Hérelle.
• Bacteriophage or Phage is a virus that infects and replicates only within the body of bacteria and no other organism.
• Highly species-specific towards their host cell. The bacteriophages only infect a single species of bacteria or even specific strains of bacteria within a species.
• Have potential to destroy bacterial suspension and called Twort d Herelle Phenomenon.
• Bacteriophages attacking Escherichia coli are called coliphages or T-phages.
• Like all viruses, phages are simple entities that consist of a core of genetic material (nucleic acid) surrounded by a protein capsid.
• The nucleic acid may be either DNA or RNA and may be double-stranded or single-stranded.
• The International Committee on Taxonomy of Viruses had classified the phages based on the nature of their nucleic acid, morphology and physicochemical properties of their virion particles. Currently, ICTV has classified the bacteriophages into nine orders, 48 families with 32 subfamilies, and 317 genera.
• By morphology phages can be tailed phages, polyhedral or filamentous phages.

ju sir agr Tphage ki structure tisee ut na chi ba chenn

[@whimsical_jg]

Sir in the assembly I.e the fourth step of lytic cycle you have written formation of virions? virions are extracellular viral particles? Can we call the assembled virus inside the host cell virion?

[@BiologyByDr.Imtiyaz]

No, an assembled virus inside the host cell is not yet called a virion. While it is on its way to becoming a fully functional virus particle, it still needs to be released from the host cell to be considered a true virion.

Sir T4 bactariophase kya hai please reply dijiyega

[@BiologyByDr.Imtiyaz]

The T4 bacteriophage is a virus that infects bacteria, specifically Escherichia coli (E. coli).
