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.
