Question Answer
Virona complete viral particle containing a nucleic acid surrounded by a protein coat
Capsidthe protein coat surrounding the viral nucleic acid
Capsomeresprotein subunits of the capsid
Envelopeconsists of a lipid layer surrounding the capsid - made up of lipids, proteins, carbohydrates
Spikescomposed of glycoproteins that project from the surface of the envelope
Hemagglutinationspikes that bind to red blood cells and clump them together
Replication: (1) Attachmentoccurs via receptors
Replication: (2) Penetrationoccurs by endocytosis of the virus
Replication: (3) Uncoatingoccurs only in animal viruses - protein coat is removed by host enzymes and the nucleic acid is exposed
Replication: (4) Biosynthesiscan be divided up into two types - DNA viruses and synthesis of RNA viruses
Replication: (5) Maturation/AssemblyDNA viruses assemble proteins are assembled in the nucleus - RNA viruses assemble proteins in the cytoplasm
Replication: (6) Releasewhole virons are released
Viroidsnaked cicular pieces of RNA, replicate autonomously and do not appear to encode for proteins
