Question

lytic vs. lysogenic cycle
feature
host cell status
virus production
viral genomes
generation speed
lytic cycle
the host cell is ______________ (another word for lysed).
new viruses are produced (immediately / gradually)
circle one
viral dna is (separate from / integrated into) host dna.
(fast / slow) : results in immediate spread
lysogenic cycle
the host cell stays ______________ and continues to divide and reproduce.
viral dna is copied and passed on, but no new viruses are assembled yet.
viral dna is (separate from / integrated into) host dna.
(fast / slow) : the virus can remain \hidden\ for many cell generations.

Explanation:

1. Lytic Cycle - Host Cell Status: In the lytic cycle, the host cell is destroyed (lysed) as new viruses exit, so the term is "destroyed".
2. Lytic Cycle - Virus Production: New viruses are made right away to quickly exit the lysed cell, so "immediately" is correct.
3. Lytic Cycle - Viral Genomes: Viral DNA remains separate from the host's DNA during active replication in the lytic cycle.
4. Lytic Cycle - Generation Speed: The lytic cycle is fast, with immediate spread of new viruses.
5. Lysogenic Cycle - Host Cell Status: The host cell remains alive and functional, dividing normally while the viral DNA is integrated.
6. Lysogenic Cycle - Virus Production: No new viruses are assembled during the latent lysogenic phase; viral DNA is just copied with host DNA.
7. Lysogenic Cycle - Viral Genomes: Viral DNA integrates into the host cell's DNA and is copied along with it.
8. Lysogenic Cycle - Generation Speed: The lysogenic cycle is slow, as the virus stays hidden through many cell generations.

Answer:

Feature	Lytic Cycle	Lysogenic Cycle
Virus Production	New viruses are produced immediately (circle one)	Viral DNA is copied and passed on, but no new viruses are assembled yet.
Viral Genomes	Viral DNA is separate from host DNA.	Viral DNA is integrated into host DNA.
Generation Speed	Fast: results in immediate spread	Slow: the virus can remain "hidden" for many cell generations.
