Biology Viruses

Front

What is the lysogenic cycle in viruses?

Back

A virus injects its genetic material into a host cell and integrates it into the host's DNA.

Front

What occurs after a virus is taken up by a host cell?

Back

The virus inserts its genetic material into the host DNA.

Front

Why are viruses considered non-living organisms?

Back

Viruses are not considered living because they cannot reproduce independently and lack cellular structure.

Front

What is the primary reason viruses need a host cell?

Back

Viruses need a host cell to reproduce.

Front

What are the two main components of a virus?

Back

A virus consists of RNA or DNA and a protein coat.

Front

What is the difference between the lytic and lysogenic cycles?

Back

In the lytic cycle, the virus replicates and causes cell lysis, while in the lysogenic cycle, the virus integrates its DNA into the host's DNA and can remain dormant.

Front

How do viruses replicate within a host cell?

Back

Viruses hijack the host's cellular machinery to replicate their genetic material and produce new virus particles.

Front

What is a viral genome?

Back

A viral genome is the genetic material of a virus, which can be either RNA or DNA.

Front

What role does the protein coat play in a virus?

Back

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

Front

What is the significance of viral latency?

Back

Viral latency allows viruses to remain dormant within a host cell, evading the immune system and potentially reactivating later.
