Questions and Answers

Which of the following is true about the structure of a virus?

A virus is made up of RNA surrounded by a protein coat called a capsid.

A virus is made up of DNA surrounded by a protein coat called a capsid.

A virus is made up of DNA or RNA surrounded by a protein coat called a capsid. (correct)

A virus is made up of DNA and RNA surrounded by a protein coat called a capsid.

What is the function of the protein capsid in a virus?

The protein capsid holds the genetic information for the virus and protects it. (correct)

The protein capsid determines the shape of the virus.

The protein capsid extends out from the membrane envelope and can interact with host cells.

The protein capsid allows the virus to be taken into a host cell more easily.

Which of the following is NOT a possible shape for a virus capsid?

Rod-shaped

Spherical

Polyhedral

Cube-shaped (correct)

Study Notes

Virus Structure

A virus consists of a protein capsid that surrounds a nucleic acid core.
The protein capsid provides protection to the viral genome and helps in the attachment of the virus to the host cell.
The nucleic acid core can be either DNA or RNA and contains the genetic material of the virus.
The shape of a virus capsid can be helical, icosahedral, or complex, but not square.
Many viruses have an additional structure called an envelope, which is a lipid bilayer that assists in the entry of the virus into the host cell.
