  2. Viral life cycle - Wikipedia

    en.wikipedia.org/wiki/Viral_life_cycle

    For the virus to reproduce and thereby establish infection, it must enter cells of the host organism and use those cells' materials. 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.

  3. Viral replication - Wikipedia

    en.wikipedia.org/wiki/Viral_replication

    Viruses may undergo two types of life cycles: the lytic cycle and the lysogenic cycle. In the lytic cycle, the virus introduces its genome into a host cell and initiates replication by hijacking the host's cellular machinery to make new copies of the virus. [12] In the lysogenic life cycle, the viral genome is incorporated into the host genome.

  4. Introduction to viruses - Wikipedia

    en.wikipedia.org/wiki/Introduction_to_viruses

    Life-cycle of a typical virus (left to right); following infection of a cell by a single virus, hundreds of offspring are released. When a virus infects a cell, the virus forces it to make thousands more viruses. It does this by making the cell copy the virus's DNA or RNA, making viral proteins, which all assemble to form new virus particles. [37]

  5. Lytic cycle - Wikipedia

    en.wikipedia.org/wiki/Lytic_cycle

    In the lytic cycle, the viral DNA exists as a separate free floating molecule within the bacterial cell, and replicates separately from the host bacterial DNA, whereas in the lysogenic cycle, the viral DNA is integrated into the host genome. This is the key difference between the lytic and lysogenic cycles.

  6. Virus - Wikipedia

    en.wikipedia.org/wiki/Virus

    A typical virus replication cycle Some bacteriophages inject their genomes into bacterial cells (not to scale) Viral populations do not grow through cell division, because they are acellular. Instead, they use the machinery and metabolism of a host cell to produce multiple copies of themselves, and they assemble in the cell. [ 74 ]

  7. Virus latency - Wikipedia

    en.wikipedia.org/wiki/Virus_latency

    Virus latency (or viral latency) is the ability of a pathogenic virus to lie dormant within a cell, denoted as the lysogenic part of the viral life cycle. [1] A latent viral infection is a type of persistent viral infection which is distinguished from a chronic viral infection. Latency is the phase in certain viruses' life cycles in which ...

  8. 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]

  9. Bacteriophage - Wikipedia

    en.wikipedia.org/wiki/Bacteriophage

    At this point they initiate the reproductive cycle, resulting in lysis of the host cell. As the lysogenic cycle allows the host cell to continue to survive and reproduce, the virus is replicated in all offspring of the cell. An example of a bacteriophage known to follow the lysogenic cycle and the lytic cycle is the phage lambda of E. coli. [53]
