COVID-19
100
The main structure of all viruses.
What is the nucleocapsid?
100
This has to occur first for any virus to enter a cell.
What is a peplomer binding to a host receptor?
100
When a virus is released because a cell ruptures and dies.
What is lysis?
100
The kind of virus that begins translation immediately with a host ribosome because it already looks like mRNA.
What are +ssRNA viruses?
100
COVID-19 is caused by this virus.
What is SARS-CoV-2?
200
The viral shape shown in the image below.
What is helical?
200
A form of entry that both naked and enveloped viruses can do.
What is endocytosis?
200
A form of viral release that is also known as exocytosis.
What is budding/blebbing?
200
The type of virus that serves as a template for RNA because it is complementary to mRNA strand.
What are -ssRNA viruses?
200
The virus that causes COVID-19 is what kind of virus (enveloped or naked, ss or ds, RNA or DNA)
What is an enveloped +ssRNA virus?
300
Identical subunits which make up the viral capsid.
What are proteins called capsomers?
300
A kind of entry where only the viral nucleocapsid enters the host cell.
What is membrane fusion?
300
All bacteriophage leave the host cell through this release method.
What is lysis?
300
The structure on +ssRNA viruses that is recognized by the ribosome to intitate translation.
What is the 5' methyl guanine cap?
300
These two kinds of environments increase your risk of contracting COVID-19.
What are cold and indoor environments?
400
The presence of this determines viral host range.
What is the complementary receptor on the host species?
400
A form of entry where a viral nucelocapsid fuses to the host cell membrane.
What is direct penetration/injection?
400
Molecular mimcry can occur because of what viral method of release.
What is budding/blebbing?
400
The amount of times a +ssRNA virus can complete translate with the hot ribosome is determine by what struture.
What is the +ssRNA's 3' poly A tail?
400
The four ways COVID-19 can be transmitted.
What are direct contact (animal-to-human), droplets (human-to-human), aerosolized, and indirect contact via fomite?
500
A kind of entry where a virus tricks a cell into thinking it's a useful molecule, like a nutrient.
What is endocytosis?
500
****** CHANGE **** Herpes viruses leave a host cell through this release method.
What is budding/blebbing?
500
Symptoms appear faster in diseases caused by which kind of ssRNA virus.
What are +ssRNA viruses?
500
The COVID-19 virus lasts in the air for ______________ and on surfaces for _______________.
What is 3 hours in air and 3 days on surfaces?
