Virus Review

Front

What is the lytic cycle?

Back

The lytic cycle is a viral life cycle in which a virus infects a host cell, replicates itself, and then causes the host cell to lyse (burst), releasing new viral particles.

Front

What is a bacteriophage?

Back

A bacteriophage is a type of virus that specifically infects bacteria.

Front

What happens during the lysogenic cycle?

Back

In the lysogenic cycle, a virus integrates its genetic material into the host cell's DNA and remains dormant until it is triggered to enter the lytic cycle.

Front

What is the difference between lytic and lysogenic cycles?

Back

The lytic cycle results in the immediate destruction of the host cell, while the lysogenic cycle allows the virus to remain dormant within the host cell.

Front

What type of virus is influenza?

Back

Influenza is a lytic virus, meaning it infects host cells and causes them to lyse immediately.

Front

Define viral replication.

Back

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

Front

What is the role of a host cell in viral infection?

Back

A host cell provides the necessary machinery and environment for a virus to replicate and produce new viral particles.

Front

What is the term for a virus that infects bacteria?

Back

Bacteriophage.

Front

What is the outcome of the lytic cycle?

Back

The outcome of the lytic cycle is the destruction of the host cell and the release of new viruses.

Front

What is a viral envelope?

Back

A viral envelope is a lipid membrane that surrounds some viruses, derived from the host cell membrane, which helps the virus enter new host cells.
