Viruses are (blank) agents.
Fiterable (can pass through a filter)
Viruses are (blank) intracellular parasites
obligate (restricted to a particular condition of life)
Can viruses make energy or proteins independently of a host cell?
Viral genomes can be RNA, DNA or both?
They can be RNA or DNA but not both
Which do viruses have, a naked capsid or an envelope morphology?
Either or :)
Are viruses living?
no, they are not
What must viruses be to endure in nature?
Viruses have been optimized by (blank) and (blank) to infect humans and other hosts
mutation and selection
Viruses must be able to use (blank) to produce their components
host cell processes
Viruses must encode any required processes not provided by the cell. T or F
Viral components (blank) assemble
What are the 2 types of viruses you can have?
naked capsid viruses enveloped viruses
What makes up a naked capsid virus?
DNA or RNA + structural proteins +/- enzymatic and nucleic acid binding proteins= nucleocapsid=naked capsid virus
What are three examples of naked capsid viruses?
papilloma virus adenovirus poliovirus
What makes up an enveloped virus?
DNA or RNA + nucleocapsid + glycoproteins and membrane= enveloped virus
What are 2 examples of an enveloped virus?
What is a bacteriophage?
a virus that infects bacteria
Many viral proteins are packaged within the virion, possibly in the (blank) layer, between the capsid and envelope
What is a virion made up of?
nucleic acid genome packaged into a protein coat (capsid or ribonucleocapsid) or a membrane (envelope)
What is a virion?
infectious virus particle
(blank) can hold a larger genome and are generally more complex
(blank) are almost visible with a light microscope (300 nm) this i 1/4 the size of staph
How do you measure virions?
What are the + RNA via DNA E viruses?
What are the +/- RNA (double capsid) viruses?
What are the -RNA E viruses?
Rhabado Filo Orthomyxo Paramyxo Bunya Arena
What are the + RNA E viruses?
Toga, Flavi, Corona
What are the + RNA N viruses?
What are the four ways you can name RNA viruses by their physical and biochemical characteristics?
+RNA (N and E) -RNA (E) +/- RNA (Double Capsid) + RNA via DNA (E)
How can you name DNA viruses by their physical and biochemical characteristics?
DNA viruses can be broken into eneveloped and naked capsids. They can then be further broken down into: enveloped-> pox, herepes, hepadna naked capsid-> polyoma, papilloma, adeno, parvo
