Not consisting of cells

Question 2

Virions

Answer 2

Inert particle that is reproductive form of a virus

Question 3

Host range

Answer 3

When viruses are able to infect cells of one or a fee species of organism

Question 4

Bacteriophage

Answer 4

Viruses that infect bacteria

Question 5

Mechanical transmission

Answer 5

Transmission occurs when an arthropod carries a viral patlwgen on the outside of its body & transmits it to a new must by physical contact

Biological transmission

Answer 6

Transmission occurs when the arthropod carries the viral pathogen inside its body & transmits it to a new host through biting

Question 62

Characteristics of Viruses

Answer 62

- infectious, acellular pathogens - obligate intracellular parasites w/host a cell-type specificity - DNA or RNA - genome surrounded by protein capsid; a phospholipid membrane studded w/viral glycoproteins in some cases - lack genes for merry products needed for successful reproduction; requires exploitation of host-cell genomes to reproduce
