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. They are extremely diverse in size, morphology, and genomic organization [1][2][3].
Detailed explanation-2: -A bacteriophage is a virus which infects a bacterium.
Detailed explanation-3: -More common, but less understood, are cases of viruses infecting bacteria known as bacteriophages, or phages.
Detailed explanation-4: -Bacteriophage enzymes destroy the bacterial cell wall from both outside and inside by hydrolyzing carbohydrate and protein components. All these proteins protect phage genetic material, secure injection of the phage nucleic acid into the bacterial cell, and promote phage propagation.
Detailed explanation-5: -A bacteriophage is a virus that infects a bacterial cell and reproduces inside it. They vary a lot in their shape and genetic material. A bacteriophage may contain DNA or RNA. The genes range from four to several thousand. Their capsid can be isohedral, filamentous, or head-tail in shape.
