Viruses and SARS-CoV-2
Lytic Life Cycle
virus infects a host cell, inserts DNA synthesizes copies of the genome, make capsid proteins assemble new viruses - capsid and genome lyse cell and infect new cells
Betacoronaviruses
family of coronaviruses
Coronavirus
family of enveloped positive-sense single-stranded RNA viruses
interferon
Protein produced by cells in response to being infected by a virus; helps other cells resist the virus.
Retrovirus
animal infecting virus
spike proteins
binds host cell receptor
reverse transcriptase
An enzyme encoded by some certain viruses (retroviruses) that uses RNA as a template for DNA synthesis.
genome
DNA or RNA encoding the instructions to infect a host cell and make more viruses
host cell
Living cell in which a virus can actively multiply or in which a virus can hide until activated by environmental stimuli
COVID19
SARS CoV 2 disease
SARS-CoV-2
Severe Acute Respiratory Syndrome - Coronavirus - 2
provirus
Viral DNA that inserts into a host genome
membrane proteins
assembly of virion envelope
prophage
bacteriophage DNA that is embedded in the bacterial host's DNA
Nucleocapsid
coats and protects RNA
zoonotic host
different wild animals
envelope proteins
minor protein needed to form virion, helps with infection
Virus
obligate intracellular molecular parasites - must infect and reproduce inside a host cell
Capsid
protein coating
RNA dependent RNA polymerase
the enzyme that uses RNA as a template to produce RNA. By in large absent from the host cells, it has to be either carried in by the virions or encoded by the viral genome
lysogenic life cycle
viral genome is incorporated into host cell genome and is replicated along with host genome
