Compare and contrast the bacteriophage lytic cycle and lysogeny by addressing (1) the rate of replication of the viral genome, (2) production of virions, and (3) effect on the host cell.

DRAW IT Redraw Figure 19.8 to show the replicative cycle of a virus with a single-stranded genome that can function as mRNA (a class IV virus).
