Viruses 2024

Front

What is an example of an animal virus?

Back

Influenza

Front

What is the name of the protein capsule that houses the genetic material of a virus?

Back

Capsid

Front

In what way does the capsid of a virus function similarly to a structure in a plant cell?

Back

It is similar to the cell wall, as it protects the virus from the external environment.

Front

What occurs during the lysogenic cycle of a virus?

Back

The virus injects its nucleic acid into the host cell, integrates into the host cell DNA, and remains dormant for a long time.

Front

In which phase does host DNA become compromised and viral DNA take over?

Back

Phase 3.

Front

What is the primary function of a virus's capsid?

Back

To protect the viral genetic material and aid in the infection of host cells.

Front

What is the difference between the lytic and lysogenic cycles of a virus?

Back

In the lytic cycle, the virus replicates and causes cell lysis, while in the lysogenic cycle, the viral DNA integrates into the host DNA and remains dormant.

Front

What type of genetic material can viruses contain?

Back

Viruses can contain either DNA or RNA as their genetic material.

Front

What is the role of viral proteins in the infection process?

Back

Viral proteins help the virus attach to and enter host cells.

Front

How do viruses differ from living organisms?

Back

Viruses cannot reproduce on their own and require a host cell to replicate.
