Question

Plaques are the result of ـــــــــــــــــــ.
A)bacteria infecting viruses
B)viruses infecting bacteria
C)viruses lysing bacteria
D)lysogens

Accepted Answer

Plaques are clear zones or patches on a bacterial lawn where the bacterial cells have been lysed (killed) by viruses called bacteriophages. As the virus replicates, it releases new virus particles, which infect nearby bacterial cells and continue the lytic cycle, resulting in the formation of more clear zones or plaques.
