Front

What is a provirus?

Back

Viral DNA that is incorporated into a host cell's chromosome.

Front

What is a prophage?

Back

Viral DNA that is integrated into the bacterial chromosome.

Front

What occurs during the lytic cycle of a virus?

Back

The virus attaches to the host cell, injects its DNA, and ultimately kills the host cell.

Front

What is a capsid?

Back

The protein coat that surrounds the genetic material of a virus.

Front

What happens in the lysogenic cycle?

Back

A virus injects its genetic material into a host cell, which can remain dormant for a period.

Front

What does 'obligate intracellular parasite' mean?

Back

An organism that requires a host cell to survive and reproduce.

Front

What is the difference between the lytic and lysogenic cycles?

Back

The lytic cycle results in the destruction of the host cell, while the lysogenic cycle integrates viral DNA into the host's genome.

Front

What is the role of tail fibers in a virus?

Back

Tail fibers help the virus attach to the host cell.

Front

What is the function of the viral envelope?

Back

The viral envelope helps the virus enter host cells and evade the host's immune system.

Front

What is genetic material in a virus?

Back

The DNA or RNA that carries the genetic information necessary for the virus to replicate.
