Virus Module Set 5

Plus strand RNA viruses: Sequence of nucleotides in genomic RNA = sequence of nucleotides in viral mRNA
Minus strand RNA viruses: Sequence of nucleotides in genomic RNA complimentary to viral mRNA
Segmented genomes: Virion contains >1 UNIQUE RNA
Viral multiplication Mechanism used depends on viral structure and genome
Viral multiplication steps Attachment to host cell Entry Uncoating (may or may not happen) Synthesis Assembly Release
Attachment (adsorption): Specific receptor attachment
Receptor determines Host preference
Viral entry and uncoating Entire genome or nucleocapsid
Viral entry and uncoating varies between Naked or enveloped viruses
Four methods of viral entry and uncoating Fusion of viral envelope w host cell Endocytosis in vesicle; endosome aids in viral uncoating Injection of nucleic acid Direct penetration of naked virus
Lytic cycle Phage life cycle that culminates with host cell bursting, releasing virions
Virulent phage Phage that lyse their host during reproductive cycle
Receptor sites: specific surface structures On host to which viruses attach
Receptor site: specific for Each virus
Receptor sites can be Proteins, lipopolysaccharides, techoic acids, pilli, etc
