BJU Life Science Virus Review

Front

What is the Lysogenic Cycle?

Back

A viral replication cycle in which the viral genetic material integrates into the host cell's DNA and remains dormant for long periods.

Front

What is the Lytic Cycle?

Back

A viral replication cycle in which the virus takes over the host cell's machinery to produce new viruses, leading to the destruction of the host cell.

Front

Which is more complex in structure: Bacteria or Viruses?

Back

Bacteria are more complex in structure than viruses.

Front

What is a Virus?

Back

A nucleic acid surrounded by a protein coat that uses other cells to reproduce.

Front

What is a Vaccine?

Back

An injection of a weakened or inactive virus that stimulates an immune response to help the body recognize and fight the real virus.

Front

What is a Host in the context of viruses?

Back

An organism that provides a suitable environment for a virus to live and reproduce.

Front

What is a Capsid?

Back

The protein coat that surrounds and protects the viral genetic material.

Front

What does it mean for a virus to be latent?

Back

It means the virus is present in the host but is not actively replicating or causing symptoms.

Front

What is the primary function of a virus?

Back

To reproduce by infecting a host cell and using its machinery.

Front

How do vaccines work?

Back

They prepare the immune system to recognize and fight specific viruses by introducing a harmless form of the virus.
