What is a virus?

Back

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

Front

What happens to cells when their membranes break apart?

Back

The virus destroys and damages a host cell.

Front

What is the first step in the viral replication cycle?

Back

The virus attaches to a host.

Front

What do bacteriophages infect?

Back

Bacteriophages infect bacteria.

Front

What is the lytic cycle?

Back

The lytic cycle is a viral replication process that results in the destruction of the host cell.

Front

What is the lysogenic cycle?

Back

The lysogenic cycle is a viral replication process where the virus integrates its genetic material into the host's DNA without destroying the host.

Front

What is the role of the capsid in a virus?

Back

The capsid is the protein shell that encases and protects the viral genetic material.

Front

What occurs during the entry phase of the lytic cycle?

Back

The virus injects its genetic material into the host cell.

Front

What is viral replication?

Back

Viral replication is the process by which a virus makes copies of itself inside a host cell.

Front

What happens during the assembly phase of the lytic cycle?

Back

New viral particles are assembled from the replicated genetic material and proteins.
