Viruses Review

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

What is the main component of a virus's structure?

Back

The main components of a virus's structure include a capsid (protein coat) and genetic material (DNA or RNA).

Front

How do viruses differ from living cells?

Back

Viruses cannot obtain or use energy, while living cells can.

Front

What is the function of the capsid in a virus?

Back

The capsid protects the viral genetic material and helps the virus attach to and enter host cells.

Front

What type of genetic material can viruses contain?

Back

Viruses can contain either DNA or RNA as their genetic material.

Front

What is the lysogenic cycle?

Back

The lysogenic cycle is a viral replication process where the virus integrates its genetic material into the host cell's DNA, allowing it to replicate indefinitely without destroying the host.

Front

What is the lytic cycle?

Back

The lytic cycle is a viral replication process that results in the destruction of the host cell and the release of new viral particles.

Front

What do all viruses have in common?

Back

All viruses contain genetic material (either DNA or RNA).

Front

Can viruses respond to their environment?

Back

Viruses do not respond to their environment in the same way living cells do; they require a host to replicate.

Front

What is a host cell?

Back

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