Classification Of Viruses
Viral Structure
Viral Replication 1 of 2
Viral Replication 2 of 2
Viral infections types
100
host cells
What is bacteria, animals, plants
100
Virion
What is complete fully developed infectious viral particle Ex: Extracellular state
100
attachment, entry/uncoating, synthesis, assembly, release
What are the 5 steps of viral replication
100
1. most DNA viruses gather in nucleus 2. Most RNA viruses grow in cytoplasm 3.capsid reassemble from viral proteins made by host cell 4.capsid full with viral RNA/or DNA 5.Number of produced viruses depends on viruses type, size, & health of host cell
What is 5 steps of assembly
100
rapid onset of disease that doesn't last long, viral numbers increase quickly& rapidly controlled by the immune system
What is Acute Viral Infection
200
DNA , RNA & multiple RNA's
genome
200
DNA or RNA
What is nucleic acid
200
chemical attraction, glycoprotein spikes/other attachment molecules resolve attachment
What is Attachment
200
enveloped viruses released by budding 1. takes part of the virus hosts plasma membrane then released, then the hosts plasma membrane grows into the new envelope virus 2. host cells is not killed by virus release but allows virus to continue replications & cause persistent infections
What is Release
200
animal virus remains dormant in host virus, can be delayed for years with no viral activity Ex: herpes/cold shores & shingles
What is Latent Viral Infection
300
Viruses Shapes
What is helical virus, polyhedral, complex
300
Capsid
What is the outer coat of proteins that that aids in attachment, protection & identity
300
Enters by penetration, fusion, or endocytosis. entry methods depend on the virus & or viral structure
What is Entry
300
disease over a long period of time (month/years) usually fatal Ex: HIV, chronic hepatitis
What is Persistent Viral Infections
400
non enveloped virus
virus with nucleic acid surrounds capsid, naked virus
400
if all the capsid enters host cell, virus has to uncoat/remove the capsid within the host cell
What is uncoating
500
virus with lipid envelope that surrounds capsid, host cell membrane during viral replication or release, & glycoprotein spikes
What is enveloped virus
500
-different methods depending on its nucleic acid & proteins so virus babies can have to reproduce -DNA viruses enter the nucleus enzymes copy viral DNA & transcribe viral DNA into viral RNA - RNA viruses usually replicate in the cytoplasm -viral RNA sent to host ribosomes & viral proteins synthesize
What is 4 steps of synthesis
