A unique group of infectious agents, simple and acellular, with a distinct reproduction pattern.

A virus particle, consisting of DNA or RNA, enclosed in a protein coat (and sometimes other layers).

Areas of cell destruction and lysis (breaking down) caused by a virus.

Damage caused by rapid cell death, often due to viral infection.

Separating particles in a suspension by spinning at different speeds; separates by size.

Separates particles in a gradient, based on density.

A method of purifying viruses by using concentrated ammonium sulfate to precipitate out some large contaminant.

Inactivation of contaminants through changes in heat or pH.

Removing cellular proteins and nucleic acids from virus preparations.

The core of a virus, made up of nucleic acid (DNA or RNA).

The protein shell that protects and delivers viral genetic material.

A 20-sided geometric protein shell, appearing spherical under a microscope.

A hollow protein cylinder with possibility to be rigid or flexible.

A membrane surrounding the nucleocapsid of some, but not all viruses.

Viruses with a capsid symmetry neither purely icosahedral nor helical.

The protein subunits that build up the complex large structures of helical and icosahedral capsids.
