  • Seasonal epidemics of influenza are also known to occur because of new variants of influenza A virus (IAV), which are generated by the introduction of mutations by viral RdRp with low fidelity. (nagasaki-u.ac.jp)
  • The virus replicates in epithe- ECs. (cdc.gov)
  • These are thought to provide a favourable environment for replication to occur, concentrating essential viral structural and nonstructural components, as well as protecting these components from host-cell pathogen recognition and innate immune responses. (gla.ac.uk)
  • Steroid compounds, which are expected to have dual functions in blocking host inflammation and MERS-CoV replication, were screened from a chemical library. (biorxiv.org)
  • Here, using the RdRp from foot-and-mouth disease virus (termed 3Dpol), we report fibril structures, solved at ~7-9 Å resolution by cryo-EM, revealing multiple conformations of a flexible assembly. (gla.ac.uk)
  • Fully animated Virus Reproductive Cycle (Replication) - Complete covers the complete replication cycle of viruses - attachment, penetration, uncoating, synthesis, assembly, maturation and release. (goalfinder.com)
  • These are 1) Virus Attachment 2) Virus Penetration 3) Virus Uncoating 4) Virus synthesis 5) Virus Assembly Maturation 6) Virus Release 7) Virus Complete Reproductive cycle (replication). (goalfinder.com)
  • Type I interferon (IFN-I) strongly inhibits viral replication and is a crucial factor in controlling virus infections and diseases. (uzh.ch)
  • This is the crucial stage for the initiation of virus life cycle within a living cell. (goalfinder.com)
  • Mutational analysis of several of these amino acids both in pUL105 and pUL70, proved that they are crucial for viral replication. (frontiersin.org)
  • Unwinding of DNA at the origin and synthesis of new strands results in replication forks growing bidirectional from the origin. (wn.com)
  • A number of proteins are associated with the replication fork which helps in terms of the initiation and continuation of DNA synthesis. (wn.com)
