0

The protein shell or coat that encloses the nucleic acid genome

Capsid

1

Seen on the surface of icosahedral virus particles

Capsomeres

2

A virus particle that is functionally deficient in some aspect of replication

Defective virus

3

Lipid containing membrane that surrounds some virus particles

Envelope

4

Virus encoded glycoprotein projections that exposed on the surface of the envelope

Peplomers

5

Protein nucleic acid complex representing packaged form of the viral genome

Nucleocapsid

6

Genome with capsid

Nucleocapsid

7

Structure for penetration or attachment

Spikes

8

Structural unit

Protomer

9

20

First step in viral replication

Attachment
Absorption
Adhesion

21

Poliovirus receptor

Immune globulin superfamily molecules

22

Rabies virus receptor

23

Influenza virus receptor

Sialic acid

24

HIV receptor

CD4

25

Epstein Barr virus receptor

Complement receptor C3d

26

General characteristic of a virus

Obligate intracellular parasite

27

Second step in viral replication

Penetration or engulfment

28

Three ways for releasing genetic material to cell

-endocytosis
-naked virions can directly penetrate the cell membrane
-fusion of the virion envelope with the plasma membrane

29

Physical separation of the viral nucleic acid from the outer structural components of the virion so that it can function

Uncoating
