As a scientist, you observe this microorganism under a microscope. Based on its shape and the fact you know it is nonliving, you would classify it as a:
virus
fungus
bacteria
prokaryotic cell
Bacteria are
Prokaryotes
Non living things
Eukaryotes
Viruses are considered
living things

partially living things
Which viral cycle takes the longest to show symptoms?
Lysogenic
Lytic
What is the first step to both viral cycles?
The virus attaches to a host
the virus injects genetic material
the host gets sick
the cell is destroyed
When the viral DNA becomes active in the lysogenic cycle, which life cycle does it enter?
lytic
lysogenic
cell cycle
DNA replication
If Andy is feeling symptoms from a virus that he contracted, the virus must be in the
lytic cycle
lysogenic cycle
the capsid bursts
the virus becomes dormant
What happens in the lysogenic cycle?
Virus goes in and leaves the host cell
Virus quickly kills the host cell
Virus injects the nucleic acid into the host cell, and the nucleic acid integrates into the host cell DNA and stays dormant for a long time
Bacteria injects DNA into a host cell
Viruses are considered
living things
non-living things
partially living things
Which cycle of a virus is most destructive to the host?
lytic cycle
lysogenic cycle
This image represents part of the
lytic cycle
lysogenic cycle
Choose the correct order of lytic cycle steps
attachment, entry, assembly, replication, release
attachment, entry, replication, assembly, release
attachment, entry, assembly, release, replication
attachment, release, assembly, replication, entry
A virus in the lysogenic state can be forced into the lytic cycle due to certain stressors
True
False
viruses are non-living because
they cannot reproduce on their own
they do not evolve

dead
What structure determines the shape of the virus?
capsid

During which cycle does a virus's genetic information become a part of the host cell's genetic information?
Lytic
Lysogenic
A virus that goes through the ______ cycle will allow you to feel symptoms immediately due to the cells lysing.
Lytic
