virus questions and slide review Flashcards
can a virus be grown?
yes with a host cell
what is a viroid?
less than viruses and essentially just RNA and effect plants
what is a virusoid
infectious RNA that needs a helper for replication
what is a prion and what makes it dangerous?
prions are misfolded proteins and can cause other proteins to unfold and cause disruption which is fatal.
bacteria, viruses, fungi, protozoans, helminth- which ones are eukaryotes
protozoans, eukaryotes, and helminths. bacteria is a prokaryote and viruses are non-cellular
bacteria, viruses, fungi, protozoans, helminth- which has cell walls
bacteria and fungi, the rest have membranes and viruses do not as they are non cellular
bacteria, viruses, fungi, protozoans, helminth- which can have intracellular infections?
all except helminths and fungi. helminths are within a hosts tissues/organs and fungi are usually on the exterior
bacteria, viruses, fungi, protozoans, helminth- which have cell membranes
all but viruses as viruses do not have cells.
bacteria, viruses, fungi, protozoans, helminth- which have ribosomes
all but viruses as they are non cellular
bacteria, viruses, fungi, protozoans, helminth- which are mostly in the microbiome
bacteria is usually found in the microbiome the others are not found as often
bacteria, viruses, fungi, protozoans, helminth- which are usually spread by vector?
bacteria, protozoans, and helminths
what is a retrovirus, and what makes it unique?
the ability for the retrovirus to blend in and cause damage. an example is HIV and AIDS
what makes something living?
ability to
metabolizes
respond to stimulus
grow
reproduce
evolve
prokaryotes and eukaryotes share what characteristics?
cell membrane and ribosomes
which has a nucleoid, prokaryotes or eukaryotes and which one has a nucleolus, nucleus, and nuclear membrane?
the prokaryote has a nucleoid and the eukaryote has the nucleolus, nucleus and nuclear membrane
