BIO205 Microbiology: I have three questions below

1) During a lytic cycle, which genes are expressed (transcribed and translated)?
Group answers:
All genes needed for viral replication.
Only genes needed by the host cell to defend itself against viruses will be expressed.
Both genes needed for viral replication and host cell genes are expressed.
(The only genes that are expressed are those for viral spikes and capsids wasn’t correct)
2)How do viruses hijack their host cells’ processes?
Group answers:
Viruses release toxins into the host cell in-between the penetration and biosynthesis phases.
The host cell’s DNA is cut into pieces by enzymes that the viral nucleic acid encodes.
The prophage acts as an enzyme and cuts up host cell DNA.
3)Latent or persistent infections occur when viruses form proviruses, but there is one other way latent infections occur. What happens in those cases?
Group answers:
Latency only occurs in viruses that infect plants.
Some latent viruses circulate in a patient’s bloodstream for years without attaching to or penetrating any host cells.
Some latent viruses remain inside the host cell nucleus as extrachromosomal, circular molecules of nucleic acid.
