Bio Viruses

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

How do viruses cause infection?

Back

Viruses cause infection by entering body cells and replicating.

Front

Why is the study of viruses considered a part of biology?

Back

The study of viruses is part of biology because they are active inside living cells.

Front

What is the structure that houses the genetic material of a virus?

Back

The protein capsule that houses the genetic material of a virus is called the capsid.

Front

What type of virus infection involves the integration of viral DNA into the host cell's DNA?

Back

The lysogenic cycle involves the integration of viral DNA into the host cell's DNA.

Front

What is the difference between the lytic and lysogenic cycles of viral replication?

Back

In the lytic cycle, the virus replicates and causes the host cell to burst, while in the lysogenic cycle, the viral DNA integrates into the host's DNA and can remain dormant.

Front

Can viruses reproduce independently?

Back

No, viruses cannot reproduce independently; they require a host cell to replicate.

Front

What is an example of a disease caused by a virus?

Back

The flu is an example of a disease caused by a virus.

Front

What is a glycoprotein in the context of viruses?

Back

A glycoprotein is a protein that has carbohydrate molecules attached to it, often found on the surface of viruses and involved in the recognition and entry into host cells.

Front

What is the role of viral proteins in infection?

Back

Viral proteins help the virus attach to and enter host cells, and they are also involved in the replication of the virus.
