Question

Quizplus · Accepted Answer

A plaque is formed when a single virus infects one bacterial cell and replicates within it, leading to the destruction of the cell and the release of new viruses. These new viruses then infect neighboring bacterial cells, leading to the formation of a localized area of bacterial cell death, which is referred to as a plaque. Plaques are often used as a measure of the viral infectivity or titer in a given sample.
