Viruses and Cells Review

Front

What distinguishes a cell from a virus?

Back

The presence of cytoplasm distinguishes a cell from a virus.

Front

What type of reproductive cycle does the SARS virus undergo?

Back

The SARS virus undergoes a lytic reproductive cycle, characterized by a quick onset of symptoms after infection.

Front

What do viruses and living cells have in common?

Back

Both viruses and living cells contain nucleic acids such as DNA or RNA.

Front

Which organisms are eukaryotic and contain a cell nucleus?

Back

Plant and animal cells are eukaryotic and contain a cell nucleus.

Front

How do viruses benefit from injecting their genetic material into host cells?

Back

Viruses benefit by using the host's machinery to replicate.

Front

What is a virus?

Back

A virus is a microscopic infectious agent that can only replicate inside the living cells of an organism.

Front

What is the main difference between lytic and lysogenic cycles?

Back

In the lytic cycle, the virus immediately replicates and destroys the host cell, while in the lysogenic cycle, the virus integrates its genetic material into the host's DNA and can remain dormant.

Front

What is a host cell?

Back

A host cell is a living cell that a virus infects and uses to replicate.

Front

What is the role of the protein coat in a virus?

Back

The protein coat protects the viral genetic material and helps the virus attach to and enter host cells.

Front

What are nucleic acids?

Back

Nucleic acids are biomolecules, such as DNA and RNA, that carry genetic information.
