  2. Viral replication - Wikipedia

    en.wikipedia.org/wiki/Viral_replication

    Viruses that contain double-stranded DNA (dsDNA) share the same kind of genetic material as all organisms, and can therefore use the replication enzymes in the host cell nucleus to replicate the viral genome. Many RNA viruses typically replicate in the cytosol, and can directly access the host cell's ribosomes to manufacture viral proteins once ...

  3. Viral life cycle - Wikipedia

    en.wikipedia.org/wiki/Viral_life_cycle

    Some viruses can "hide" within a cell, which may mean that they evade the host cell defenses or immune system and may increase the long-term "success" of the virus. This hiding is deemed latency. During this time, the virus does not produce any progeny, it remains inactive until external stimuli—such as light or stress—prompts it to activate.

  4. Viral pathogenesis - Wikipedia

    en.wikipedia.org/wiki/Viral_pathogenesis

    Typical sites of virus entry into the body: The first steps of viral infection is determined by the site at which the virus implants into the body. This would subsequently dictate the mechanisms of viral pathogenesis. Transmission from a host with an infection to a second host; Entry of the virus into the body; Local replication in susceptible ...

  5. Viral strategies for immune response evasion - Wikipedia

    en.wikipedia.org/wiki/Viral_strategies_for...

    Viruses of the flaviviridae Family, such as hepatitis C virus, have developed complex viral mechanisms to rearrange the cell membrane, creating a membranaceous web designed to house viral replication machinery. These viruses utilize endogenous host cell nuclear pore complex proteins to shield viral RNA from Pattern Recognition Receptors by ...

  6. Human virome - Wikipedia

    en.wikipedia.org/wiki/Human_virome

    The healthy virome consists of three distinct components: (i) viruses that systematically enter the human organism, primarily, with food, but do not replicate in humans; (ii) viruses infecting prokaryotes and, possibly, unicellular eukaryotes that comprise the healthy human microbiome; and (iii) viruses that actually replicate and persist in ...

  7. Viral entry - Wikipedia

    en.wikipedia.org/wiki/Viral_entry

    Once inside the cell, the virus leaves the host vesicle by which it was taken up and thus gains access to the cytoplasm. Examples of viruses that enter this way include the poliovirus, hepatitis C virus, [14] and foot-and-mouth disease virus. [15] Many enveloped viruses, such as SARS-CoV-2, also enter the cell through endocytosis. Entry via the ...

  8. RNA virus - Wikipedia

    en.wikipedia.org/wiki/RNA_virus

    All known RNA viruses, that is viruses that use a homologous RNA-dependent polymerase for replication, are categorized by the International Committee on Taxonomy of Viruses (ICTV) into the realm Riboviria. [3] This includes RNA viruses belonging to Group III, Group IV or Group V of the Baltimore classification system as well as Group VI.

  9. Self-replication - Wikipedia

    en.wikipedia.org/wiki/Self-replication

    Self-replication is a fundamental feature of life. It was proposed that self-replication emerged in the evolution of life when a molecule similar to a double-stranded polynucleotide (possibly like RNA) dissociated into single-stranded polynucleotides and each of these acted as a template for synthesis of a complementary strand producing two double stranded copies.
