|
virus
|
a nonliving particle made up of nucleic acid and a protein coat/or nucleic acid and a lipoprotein coat
|
|
|
Wendell Stanley
|
crystallized tobacco mosaic virus
|
|
|
capsid
|
protein coat that surrounds viruses
|
|
|
envelope
|
bilipid membrane that surrounds the capsid on some viruses
|
|
|
provirus
|
viral dna that is inserted into a host cell's chromosome
|
|
|
retrovirus
|
contain reverse transcriptase as well as rna
|
|
|
reverse transcriptase
|
uses rna as a template to make dna, which then inserts into the host cell's genome
|
|
|
bacteriophages
|
viruses that can infect bacteria
|
|
|
lytic cycle
|
cycle in which a a virus invades a host cell, produces new viruses, and ruptures the host cell when releasing newly formed viruses
|
|
|
virulent
|
viruses that reproduce only by the lytic cycle
|
|
|
lysogenic cycle
|
infection cycle that allow viruses to hide in their host cell for days, months, or years
|
|
|
temperate virus
|
virus whose replication includes the lysogenic cycle
|
|
|
vector
|
an intermediate host that transfers a pathogen or parasite to another organism
|
|
|
hepatitis
|
inflammation of the liver
|
|
|
macrophages
|
immune system cells
|
|
|
protease inhibitors
|
class of drus that blocks the synthesis of new viral capsules
|
|
|
oncogenes
|
viral genes that cause cancer [by blocking the normal controls on cell reproduction]
|
|
|
proto-oncogenes
|
controls cell growth
|
|
|
emerging diseases
|
illnesses caused by new or reappearing infectious agents that typically exist in animal populations and can infect humans that interact with them
|
|
|
inactivated virus
|
virus that is not able to replicate in a host
|
|
|
attenuated virus
|
a weakened form of a virus that cannot cause disease
|
|
|
acyclovir
|
drug that blocks the dna polymerase of herpes and chickenpox
|
|
|
prions
|
infections protein particles that do not have a genome
|
|
|
viroids
|
smallest known particles that are able to replicate
made up of a short circular strand of rna without a capsid |
