In the following picture, which is a nucleocapsid and which one is a nucleoprotein
|
The image on the left is a nucleocapsid because it is literally a naked virus with a capsid surrounded by an envelope. The picture on the right shows a helical virus without a capsule and placed in an envelope thus necleoprotein.
|
|
|
List the Naked (nonenveloped virsuses).
Also, which ones are RNA and DNA viruses? hint* Naked CPR PAPP smear |
RNA:
Calicivirus Picornavirus Reovirus DNA: Parvovirus Adenovirus Papilloma Polyoma |
|
|
List all DNA viruses:
*hint All DNA viruses are HHAPPPPy viruses |
Herpesvirus
Hepadnavirus Adenovirus Parvovirus Papillomavirus Polyomavirus Poxvirus |
|
|
1.) DNA viruses are all double stranded Except _________
2.) DNA viruses that are enveloped are? 3.) Which DNA virus is partially double stranded (Gapped)? |
1.) Parvo is ssDNA
2.)Herpes Hepadna Pox 3.) Hepadnavirus |
|
|
What are the negative-stranded RNA viruses?
*Always Bring Polymerase Or Fail Replication Which ones are enveloped? |
Arena
Bunya Paramyxo Orthomyxo Filo Rhabdo All of these are enveloped |
|
|
What are the positive stranded RNA viruses? What is the only RNA virus that is Double stranded?
*Think positive things |
Non-Enveloped:
Picorna Hepe Calici Enveloped: Flavi Toga Retro Corona The only double stranded RNA virus is Reovirus, however it is a naked virus |
|
|
Of the negative -ssRNA viruses, which ones are enveloped? Helical?
*Always Bring Polymerase Or Fail replication |
All -ssRNA viruses are enveloped and helical
|
|
|
All +ssRNA viruses are icosahedral EXCEPT:
which ones are enveloped? |
Coronavirus is the only +ssRNA virus that is helical and not icosahedral
Fla To Re Co are envelo Flavi Toga Retro Corona |
|
|
A complete, mature, and infective viral particle?
How is this different than the definition of a virus? |
Virion
A virus is a generic term that not only refers to the virion, but also to virus-like particles which are non-infectious. |
|
|
A cell that possesses all of the required cellular components that allows a virus to complete its replicative cycle is correctly called:
|
Permissiveness
Permissive cells are usually susceptible, which means they have specific surface receptors required for viral adhesion. |
|
|
Explain the general assembly of a capsid.
|
Five protomers-->Capsamere (pentamer)-->Capsid
12 pentamers form a capside |
|
|
Some viruses possess a structural layer called a matrix. What is it?
|
Serves either as a shell linking the nucleoprotein to the envelope or welding the nucleocapsid to the envelope.
