Viruses

Front

What do viruses need to reproduce?

Back

They need a host cell.

Front

Reasons that viruses are considered to be nonliving are because:

Back

They are not cellular, they cannot reproduce on their own, they cannot make proteins, all of the above.

Front

Which viral life cycle causes the host cell to burst open?

Back

Lytic.

Front

Can viruses reproduce on their own?

Back

False.

Front

What part of the phage is the DNA?

Back

B.

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 structure of a virus?

Back

Viruses typically consist of genetic material (DNA or RNA) surrounded by a protein coat called a capsid.

Front

What is the difference between lytic and lysogenic cycles?

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 replicates along with it.

Front

What is a host cell?

Back

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

Front

Why can't viruses be classified as living organisms?

Back

Viruses cannot carry out metabolic processes on their own and require a host cell to reproduce.
