virus life cycles

Cards (8)

  • Reverse transcriptase is found in viruses with RNA genomes and synthesizes a double-stranded DNA copy of a viral RNA gemome
  • Integrase integrates the viral DNA into the host DNA which will now produce viral proteins from the viral DNA
  • the lytic cycle is characterized by massive reproduction of the virus resulting in host cell lysis therefore it is virulent
  • in the lysogenic cycle, the virus enters into a latent state where it does not reproduce but remains dormant within the host cell until triggered to become active again
  • in the lytic cycle viral DNA replicated separately from the bacterial chromosome
  • in the lysogenic cycle viral DNA is integrated into the bacterial chromosome
  • RNA-dependent-RNA polymerase synthesizes negative sense ssRNA in sars-cov-2
  • the information flow of gene expression in the sars-cov-2 life cycle is RNA +, RNA -, RNA +, protein
