What is a virus?

• A particle made of proteins, nucleic acids, and sometimes lipids that can replicate only by infecting living cells.

• A virus that infects bacteria.

• A particle that embeds DNA into the DNA of the host cell.

• I don’t know

What is a capsid?

• A virus that has RNA as its genetic information.

• A virus that infects bacteria.

• The protein coat that surrounds a virus.

• I don’t know

True or false: Lysogenic information is the type of infection in which a virus embeds its DNA into the DNA of the host cell and is replicated along with the host’s cell DNA.

• True

• False

What is a prophage?

• An infection which the virus enters and cell, makes copies of itself, then makes the cell burst.

• Bacteriophage DNA that is embedded in the bacterial host’s DNA.

• I don’t know

• A virus that infects bacteria.

A virus entering a cell, making copies of itself then making the cell burst is called

In DNA and RNA, you know that bacteriophage is a type of virus that infects

What is a retrovirus?

• I don’t know

• A virus that can infect bacteria.

• A virus that infects DNA.

• An RNA virus that contains RNA as its genetic information.

True or False: Lysogenic infection is when a virus embeds its DNA of the host cell and is replicated along with the host cells DNA.

• True

• False
