Dave Bachoon Exam 3 microbiology || Solved Correctly.
virus correct answers vary is size as well as shape, use electron microscope and are smaller than
bacteria
virus infect.. correct answers bacteria, fungi, protists, only considered alive when it is inside a
cell,
contain either DNA or RNA and a protein coat, multiply inside a cell ARE NOT sensitive to
antibiotics
host range of viruses correct answers majority only infect one host,
bacteriophage correct answers viruses that infect bacteria
Virion correct answers a complete virus, can exist outside of host cell
how are they classified correct answers by difference on their protein coat
capsid correct answers protein coat over nucleic acid
what are capsids made up of correct answers capsomeres
host immune system correct answers produces antibodies to the virus surface proteins, viruses
can mutate these proteins at a high rate and results multiple infections by the same virus
helical virus correct answers long rods with hallow center
polyhedral correct answers Icosahedral shape, polio virus
, envelope virus correct answers have an envelope \, roughly spherical, flu and herpes
taxonomy correct answers a viral species- same genetic information and the same ecological
niche
growing virus correct answers animal viruses are grown, in living animal ex; mice and rabbits
embryonated eggs correct answers vaccine production
cell cultures correct answers continues cell lines, immortal cells, obtained from cancer cells
viral multiplication correct answers 2 possible mechanisms
lytic cycle correct answers host cell is destroyed
lysogenic cycle correct answers host cell remains alive
lytic cycle process correct answers Attachment, penetration, biosynthesis, maturation, release
lysogenic cycle process correct answers stays in this stage for many generations, called a
prophage
Adenoviridae correct answers common cold, respiratory disease
Poxviridae correct answers - pus filled lesions
- Ex: small pox
Herpesviridae correct answers 100 types, cold sores; chicken pox
