Is a virus living?
It’s on the borderline between living and non-living.
What do viruses have instead of a cellular structure?
They have a core of genetic material (DNA or RNA, but not both) surrounded by a protein coat.
In what way are viruses like living things?
They can only perform one of the seven vital functions, reproduction.
What do all viruses have?
A capsid or head region that contains genetic material.
What is the capsid made of?
Protein and glycoproteins.
What is the purpose of a tail region?
The tail aids in binding to the host cell’s surface and in introducing virus genetic material to the host cell.
