WebAfter entering the host cell, the virus synthesizes virus-encoded endonucleases to degrade the bacterial chromosome. It then hijacks the host cell to replicate, transcribe, and translate the necessary viral components (capsomeres, sheath, base plates, tail fibers, and viral enzymes) for the assembly of new viruses. WebIt is a common misconception that feeding or starving a virus is the key to curing an infection. However, the truth is that the term “feeding” or “starving” a virus is not entirely accurate, as viruses do not have metabolic processes like living organisms.
