  2. Hepatitis A - Wikipedia

    en.wikipedia.org/wiki/Hepatitis_A

    Hepatitis A is an infectious disease of the liver caused by Hepatovirus A (HAV); [7] it is a type of viral hepatitis. [8] Many cases have few or no symptoms, especially in the young. [ 1 ] The time between infection and symptoms, in those who develop them, is two–six weeks. [ 2 ]

  3. Viral replication - Wikipedia

    en.wikipedia.org/wiki/Viral_replication

    Viral replication is the formation of biological viruses during the infection process in the target host cells. Viruses must first get into the cell before viral replication can occur. Through the generation of abundant copies of its genome and packaging these copies, the virus continues infecting new hosts. Replication between viruses is ...

  4. Viral life cycle - Wikipedia

    en.wikipedia.org/wiki/Viral_life_cycle

    To enter the cells, proteins on the surface of the virus interact with proteins of the cell. Attachment, or adsorption, occurs between the viral particle and the host cell membrane. A hole forms in the cell membrane, then the virus particle or its genetic contents are released into the host cell, where replication of the viral genome may commence.

  5. Viral transformation - Wikipedia

    en.wikipedia.org/wiki/Viral_transformation

    Viral transformation is the change in growth, phenotype, or indefinite reproduction of cells caused by the introduction of inheritable material. Through this process, a virus causes harmful transformations of an in vivo cell or cell culture. The term can also be understood as DNA transfection using a viral vector. Figure 1: Hepatitis-B virions

  6. Baltimore classification - Wikipedia

    en.wikipedia.org/wiki/Baltimore_classification

    Baltimore classification groups viruses together based on their manner of mRNA synthesis. Characteristics directly related to this include whether the genome is made of deoxyribonucleic acid (DNA) or ribonucleic acid (RNA), the strandedness of the genome, which can be either single- or double-stranded, and the sense of a single-stranded genome, which is either positive or negative.

  7. Viral hepatitis - Wikipedia

    en.wikipedia.org/wiki/Viral_hepatitis

    Hepatitis D is caused by the hepatitis D virus (HDV), or hepatitis delta virus; it belongs to the genus Deltavirus. HDV is similar to a satellite virus as it can only propagate in the presence of the hepatitis B virus, depending on the helper function of HBV for its replication and expression. It has no independent life cycle, but can survive ...

  8. Hepatitis A virus cis-acting replication element - Wikipedia

    en.wikipedia.org/wiki/Hepatitis_A_virus_cis...

    In molecular biology, the hepatitis A virus cis-acting replication element (CRE) is an RNA element which is found in the coding region of the RNA-dependent RNA polymerase in hepatitis A virus (HAV). It is larger than the CREs found in related Picornavirus species, but is thought to be functionally similar.

  9. Viral entry - Wikipedia

    en.wikipedia.org/wiki/Viral_entry

    Viral entry is the earliest stage of infection in the viral life cycle, as the virus comes into contact with the host cell and introduces viral material into the cell. The major steps involved in viral entry are shown below. [1] Despite the variation among viruses, there are several shared generalities concerning viral entry. [2]
