What is a virus?

Back

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

How do viruses reproduce?

Back

Viruses can only reproduce by infecting a host cell and using the host's cellular machinery to replicate.

Front

What is the protein coat of a virus called?

Back

The protein coat of a virus is called a capsid.

Front

What is the primary function of the viral capsid?

Back

The primary function of the viral capsid is to protect the viral genetic material and assist in the attachment to host cells.

Front

What are the two main types of nucleic acids found in viruses?

Back

The two main types of nucleic acids found in viruses are DNA and RNA.

Front

What is a bacteriophage?

Back

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

Front

What is the first step in the viral infection process?

Back

The first step in the viral infection process is attachment to the host cell.

Front

What happens during the replication stage of a virus?

Back

During the replication stage, the virus's genetic material is copied and new viral components are produced.

Front

What is the role of viral proteins?

Back

Viral proteins play a crucial role in the virus's ability to infect host cells and replicate.

Front

What is the difference between lytic and lysogenic cycles?

Back

In the lytic cycle, the virus immediately replicates and destroys the host cell, while in the lysogenic cycle, the viral DNA integrates into the host's genome and can remain dormant.
