What is a capsid?

Back

A protective coat made of protein that surrounds the viral genetic material.

Front

What happens when viral DNA becomes active in the lysogenic cycle?

Back

It enters the lytic cycle.

Front

How are viruses classified in terms of living or non-living?

Back

Viruses are considered non-living because they cannot reproduce on their own.

Front

What occurs during the lysogenic cycle?

Back

The virus's genetic information becomes part of the host cell's genetic information.

Front

What is the role of viral RNA or DNA?

Back

It carries the genetic information necessary for the virus to replicate.

Front

What is the difference between the 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 DNA and can remain dormant.

Front

What is a host cell?

Back

A living cell that a virus infects and uses to replicate.

Front

What is viral replication?

Back

The process by which a virus makes copies of itself inside a host cell.

Front

What is a viral infection?

Back

An invasion of a host organism by a virus, leading to disease.
