  2. 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 ...

  3. Orthornavirae - Wikipedia

    en.wikipedia.org/wiki/Orthornavirae

    Negative-strand RNA viruses have genomes that function as templates from which mRNA can be synthesized directly by RdRp. [8] Replication is the same process but executed on the positive sense antigenome, during which RdRp ignores all transcription signals so that a complete -ssRNA genome can be synthesized.

  4. Viral transformation - Wikipedia

    en.wikipedia.org/wiki/Viral_transformation

    Figure 3: Examples of endocytosis. The process is similar in animal cells. In most cases, rather than viral DNA being injected into an animal cell, a section of the membrane encases the virus and the cell then absorbs both the virus and the encasing section of the membrane into the cell. This process, called endocytosis, is shown in Figure 3. [5]

  5. Cap snatching - Wikipedia

    en.wikipedia.org/wiki/Cap_snatching

    Transcription of mRNAs initiated by viral polymerase using cap snatching. The first step of transcription for some negative, single-stranded RNA viruses is cap snatching, in which the first 10 to 20 residues of a host cell RNA are removed (snatched) and used as the 5′ cap and primer to initiate the synthesis of the nascent viral mRNA. [1]

  6. Introduction to viruses - Wikipedia

    en.wikipedia.org/wiki/Introduction_to_viruses

    Viruses force the cell to make new proteins that the cell does not need, but are needed for the virus to reproduce. Protein synthesis consists of two major steps: transcription and translation. [34] Transcription is the process where information in DNA, called the genetic code, is used to produce RNA copies called messenger RNA (mRNA).

  7. Bromoviridae - Wikipedia

    en.wikipedia.org/wiki/Bromoviridae

    Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive stranded rna virus transcription, using the internal initiation model of subgenomic rna transcription is the method of transcription. The virus exits the host cell by tubule-guided viral movement.

  8. Virgaviridae - Wikipedia

    en.wikipedia.org/wiki/Virgaviridae

    Replication follows the positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcription. Translation takes place by leaky scanning, and suppression of termination. The virus exits the host cell by tripartite non-tubule guided viral movement, and monopartite non-tubule guided viral movement.

  9. Morbillivirus - Wikipedia

    en.wikipedia.org/wiki/Morbillivirus

    Viral replication is cytoplasmic. Entry into the host cell is achieved by virus attaching to host cell. Replication follows the negative-stranded RNA virus replication model. Negative-stranded RNA virus transcription, using polymerase stuttering, through co-transcriptional RNA editing is the method of transcription. Translation takes place by ...
