Viruses

Front

What are viruses considered to be nonliving?

Back

They are not cellular, they cannot reproduce on their own, and they cannot make energy.

Front

What is the first step in both the lytic and lysogenic cycles?

Back

The virus attaches to a host.

Front

Do viruses need to be specific about the type of cell they attach to?

Back

Yes, viruses are specific to the type of cell they infect.

Front

What is the lytic cycle?

Back

A viral replication process that results in the destruction of the host cell.

Front

What is the fifth step in the lytic cycle?

Back

Release.

Front

What is the lysogenic cycle?

Back

A viral replication process where the virus integrates its genetic material into the host cell's DNA.

Front

What is a host cell?

Back

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

Front

What is viral replication?

Back

The process by which a virus makes copies of itself inside a host cell.

Front

What happens during the entry step of the lytic cycle?

Back

The virus injects its genetic material into the host cell.

Front

What is the role of viral proteins in the lytic cycle?

Back

They help assemble new virus particles and facilitate the release of new viruses.
