Terminology

Question 1

Virion

Answer 1

fully assembled, infective virus particle

- contains genetic material surrounded by a protein shell and in some cases a lipid envelope

Question 2

Capsomer

Answer 2

capsids are composed of smaller repetitive subunits termed capsomers

• Capsomers are arranged in two fundamental patterns of structural symmetry:
  
  • Iscosahedral
  • Helical

Question 3

Viral envelop

Answer 3

In many but not all viruses. This is a lipid membrane that surrounds the capsid
All Helical shaped viruses are surrounded in an envelppe

Question 4

Envelope glycoproteins

Answer 4

these are coded for by the viral nucleic acid. These are also called peplomers or spikes

Question 5

Capsid

Answer 5

Protien shell that surrounds the viral nucleic acid

Question 6

Protomer

Answer 6

Each capsomer is comprised of individual proteins called protomers that self assemble
