What is a virus?

Back

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

Front

Are viruses considered living things?

Back

No, viruses are not considered living things because they are not made of cells and cannot carry out metabolic processes on their own.

Front

What is the size comparison between viruses and cells?

Back

Viruses are generally much smaller than cells.

Front

What do bacteriophages specifically infect?

Back

Bacteriophages specifically infect bacteria.

Front

What is the lytic cycle of a virus?

Back

The lytic cycle is a viral reproductive cycle in which the virus takes over a host cell, replicates, and causes the cell to burst, releasing new viruses.

Front

What is the lysogenic cycle of a virus?

Back

The lysogenic cycle is a viral reproductive cycle in which the virus integrates its genetic material into the host cell's DNA and remains dormant until activated.

Front

What are the main components of a virus?

Back

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

Front

How do viruses reproduce?

Back

Viruses reproduce by infecting a host cell and using the host's cellular machinery to replicate their genetic material and produce new virus particles.

Front

What is the role of the protein coat in a virus?

Back

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

Front

Can viruses infect all types of organisms?

Back

No, viruses are specific to certain types of organisms; for example, some viruses infect only plants, while others infect animals or bacteria.
