What are the 2 main parts of a virus?
Capsid, nucleic acid
200
Define Antigen
A protein on the surface of the pathoGEN that your body uses to identify it
200
What does reverse transcriptase do?
Builds viral DNA from viral RNA (thus going backwards)
200
What are the correct sequence of events for the lytic cycle?
Attachment, entry of genetic material, replication, assembly, release
200
What is the 2 name naming system?
Binomial Nomenclature
300
What are the 3 virus shapes?
Icosahedral, complex, helical
300
Define immunity.
When your body has enough antibodies so that it is unaffected by a pathogen
300
What does integrase do?
Integrates viral dna into host dna
300
What is the correct sequence of events for lysogenic cycle?
Attachment, entry of genetic material, latent period, replication, assembly, release
300
What are the 3 domains of life?
Bacteria, Archaea, Eukarya
400
A? B? E? F? G?
A - Capsid
B - Nucleic Acid
E - Sheath
F - Tail Fibers
G- Baseplate
400
Which vaccine type uses another virus to deliver antibodies to your cells?
Nucleic acid vaccines
400
1. attachment. 2. entry. 3. replication. 4. assembly. 5. release.
400
What occurs during the latent period of lysogenic phase?
Mitosis and normal cell function
400
What are the 6 kingdoms of life?
Bacteria, Archaea, Plantae, Animalia, Fungi, Protista
500
T/F -
Viral particle also called a virion.
Viruses = 10-1000 mm
Viruses can have DNA or RNA.
Viruses are considered intercellular parasites.
T
F
T
F - inTRAcellular
500
Which is the least effective vaccine type?
Subunit vaccines
500
What are the 2 enzymes specific to retroviruses and what is their function?
Reverse transcriptase - performs backwards transcription to build viral DNA
Integrase - integrates viral DNA and host DNA
500
What is the difference between lytic and lysogenic cycle?
Lysogenic - virus merges it's DNA with host DNA and allows the cell to undergo normal cell division through mitosis, creating many more infected cells
500
What are the levels in order?
Domain. Kingdom. Phylum. Class. Order. Family. Genus. Species.
