1

Viruses are (blank) agents.

Fiterable (can pass through a filter)

2

Viruses are (blank) intracellular parasites

obligate (restricted to a particular condition of life)

3

Can viruses make energy or proteins independently of a host cell?

NOOOOO

4

Viral genomes can be RNA, DNA or both?

They can be RNA or DNA but not both

5

Which do viruses have, a naked capsid or an envelope morphology?

Either or :)

6

Are viruses living?

no, they are not

7

What must viruses be to endure in nature?

infectious

8

Viruses have been optimized by (blank) and (blank) to infect humans and other hosts

mutation and selection

9

Viruses must be able to use (blank) to produce their components

host cell processes

10

Viruses must encode any required processes not provided by the cell. T or F

T

11

Viral components (blank) assemble

self

12

What are the 2 types of viruses you can have?

naked capsid viruses enveloped viruses

13

What makes up a naked capsid virus?

DNA or RNA + structural proteins +/- enzymatic and nucleic acid binding proteins= nucleocapsid=naked capsid virus

14

What are three examples of naked capsid viruses?

papilloma virus adenovirus poliovirus

15

What makes up an enveloped virus?

DNA or RNA + nucleocapsid + glycoproteins and membrane= enveloped virus

16

What are 2 examples of an enveloped virus?

herpesvirus retrovirus

17

What is a bacteriophage?

a virus that infects bacteria

18

Many viral proteins are packaged within the virion, possibly in the (blank) layer, between the capsid and envelope

tegument

19

What is a virion made up of?

nucleic acid genome packaged into a protein coat (capsid or ribonucleocapsid) or a membrane (envelope)

20

What is a virion?

infectious virus particle

21

(blank) can hold a larger genome and are generally more complex

larger virions

22

(blank) are almost visible with a light microscope (300 nm) this i 1/4 the size of staph

poxviruses

23

How do you measure virions?

in nanometers

24

What are the + RNA via DNA E viruses?

Retro

25

What are the +/- RNA (double capsid) viruses?

Reo

26

What are the -RNA E viruses?

Rhabado Filo Orthomyxo Paramyxo Bunya Arena

27

What are the + RNA E viruses?

Toga, Flavi, Corona

28

What are the + RNA N viruses?

Picrona, Calici

29

What are the four ways you can name RNA viruses by their physical and biochemical characteristics?

+RNA (N and E) -RNA (E) +/- RNA (Double Capsid) + RNA via DNA (E)

30

How can you name DNA viruses by their physical and biochemical characteristics?

DNA viruses can be broken into eneveloped and naked capsids. They can then be further broken down into: enveloped-> pox, herepes, hepadna naked capsid-> polyoma, papilloma, adeno, parvo
