bacterial rickettsias

obligatory intracellular parasite

Host range

Viruses require . . .

Both DNA and RNA to create viral proteins

a complex cell wall to help them get into the host cell

organelles for glucose synthesis

Enzymes from host cells for protein synthesis and ATP generation

Identify a requirement that viruses need to be able to invade a host cell.

A virus must able to chemically interact with receptor sites on the cell wall or cell membrane of the host cell

A virus must be able to duplicate the metabolism of the host cell

A virus must contain a cell wall identical to that of its host cell

A virus must use a covalent bond to interact with its host cell wall or cell membrane

Complete, fully developed infectious viral particle which has a nucleic acid and protein coat.

lysozyme

prion

viroid

viron

In viral nucleic acids

DNA is the primary genetic material

RNA is the primary genetic material and DNA must be made.

DNA or RNA can be the primary genetic material but it will never have both.

mRNA is the primary genetic material and carries the viral message to the host.

What determines the structure of the capsid?

The viral genes.

The viral enzymes.

The viral proteins.

The viral carbohydrate markers.

The viral capsid made of capsomeres is composed of . . .

a carbohydrate coat

a protein coat

a nucleic acid coat

a lipid coat

10.

Has a cylindrical capsid. Ebola and rabies are examples

Polyhedral virus

Complex virus

Enveloped virus

Helical virus

11.

These viral structures are external to the envelope are used for attachment to the host cell.

pilli

glycocalyx

spikes

capsomeres

12.

The outer coating of a virus that may come from the host cell consisting of lipids, proteins and carbohydrates

capsid

envelope

tail sheath

capsomere

13.

Cells that can be maintained through many numbers of generations –

immortal cells

continuous cell lines

cell culture

plaques

viral culture

14.

Naked RNA with no protein coat – sometimes found in plants

Virion

immature virus

viroid

host

15.

How is influenza an example of a zoonotic disease?

a disease that can pass from species to species

a disease that stays in one species

a disease that is a

dead end disease

16.

a virus that causes cancer

oconogenic virus

viroid

bacterophage

prophage virus

17.

What happens to the virus during the eclipse phase?

The load of virus in the blood stream is increasing

the load of virus in the blood stream decreases because the virus is replicating in cells

White Blood cells are killing viruses

The virus has lysed the cell and the load of virus is increasing in the blood stream
