Multiple Choice
Which viral life cycle typically kills its host cell by rupturing (lysing) the cell to release newly produced virions?
A
Latent (episomal) cycle with periodic reactivation without host-cell lysis
B
Chronic productive infection characterized primarily by budding without immediate host-cell lysis
C
Lytic cycle
D
Lysogenic cycle
Verified step by step guidance1
Understand the different viral life cycles: lytic, lysogenic, latent (episomal), and chronic productive infection.
Recall that the lytic cycle involves the virus taking over the host cell's machinery to produce many new virions, which eventually causes the host cell to rupture (lyse) and release these virions.
Recognize that the lysogenic cycle involves integration of viral DNA into the host genome without immediate destruction of the host cell, allowing the virus to replicate passively with the host.
Note that latent (episomal) cycles involve the virus existing in the host cell without causing lysis, with possible periodic reactivation but no immediate cell rupture.
Understand that chronic productive infections release new virions primarily by budding, which does not immediately kill the host cell, unlike the lytic cycle.
