Detailed explanation-1: -Visible, clear, well-defined patches in a monolayer of virus-infected cells in a culture are called. lysogeny.
Detailed explanation-2: -cytopathic effects. Visible, clear, well-defined patches in a mono-layer of virus-infected cells in a culture are called : plaques.
Detailed explanation-3: -The assay relies on determining the number of plaque forming units (pfu) created in a monolayer of virus-infected cells. Plaques form when a virus-infected cell Iyses, leading to a subsequent cycle of infection and lysis of neighboring cells.
Detailed explanation-4: -Plaque assays remain one of the most accurate methods for the direct quantification of infectious virons and antiviral substances through the counting of discrete plaques (infectious units and cellular dead zones) in cell culture.
Detailed explanation-5: -Viral plaques present themselves as areas clear of cellular growth in a lawn of bacterial cells or monolayer of eukaryotic cells following viral infection.
