Virus Replication Review

What is a key characteristic that distinguishes viruses from bacteria and fungi?

• Viruses are prokaryotic cells.

• Viruses are eukaryotic cells.

• Viruses are not considered cells.

• Viruses are larger than cells.

What is one thing all viruses have in common?

• All viruses have spikes

• All viruses have an outer lipid envelope

• All viruses have some type of genetic material

• Hall viruses have tail fibers

What is the function of the capsid?

• to protect the virus' genetic material

• to help the virus attach to the host cell

• to replicate viral genetic material

• to speed up the virus reproductive process

True or false - viruses need a living host cell to replicate

• True

• False

Which of the following accurately describes a step in the lytic cycle of viral replication?

• The virus integrates its genetic material into the host cell's genome and remains dormant.

• The host cell replicates its own genetic material along with the viral genetic material.

• The virus attaches to a host cell, injects its genetic material, and uses the host's machinery to produce new viruses, eventually causing the host cell to burst.

• The virus only replicates when the host cell experiences a lack of food.

What happens to the viral genetic material during the lysogenic cycle?

• It immediately takes over the host cell's machinery to produce new viruses.

• It integrates into the host cell's genetic material and is replicated along with it.

• It is destroyed by the host cell's immune system.

• It remains outside the host cell, waiting for a trigger to enter.

Why is it challenging to develop effective long-term treatments for many viral infections, such as HIV?

• Viruses are too small to be targeted by medication.

• Viruses can rapidly mutate, making existing treatments ineffective.

• Viruses only infect non-living cells, which are hard to treat.

• Viruses do not have genetic material, so there's nothing to target.
