Virus structure

Capsid

Protective covering of the genetic material or genome (similar to the nucleus of the cell)

Protein
envelope

The outer covering the virus (similar
to the cell membrane, but made of
proteins)

Projections

Structures on the outside of the virus that allows it to attach to the host cell

Draw

Draw a virus and label the (1) capsid, (2) DNA, and (3) surface protein markers
