  2. Gammaretrovirus - Wikipedia

    en.wikipedia.org/wiki/Gammaretrovirus

    The virus is now referred to as a provirus, which means the gammaretrovirus DNA has integrated into the host cell genome and is now the template for the formation of viral mRNA and genomic RNA. Double-stranded DNA is transcribed by Pol II and will produce both spliced and unspliced RNA strands, these spliced RNA strands will leave the host cell ...

    en.wikipedia.org/wiki/Double-stranded_RNA_viruses

    Double-stranded RNA viruses (dsRNA viruses) are a polyphyletic group of viruses that have double-stranded genomes made of ribonucleic acid.The double-stranded genome is used as a template by the viral RNA-dependent RNA polymerase (RdRp) to transcribe a positive-strand RNA functioning as messenger RNA (mRNA) for the host cell's ribosomes, which translate it into viral proteins.

  4. RNA therapeutics - Wikipedia

    en.wikipedia.org/wiki/RNA_Therapeutics

    The main types of RNA therapeutics are those based on messenger RNA (mRNA), antisense RNA (asRNA), RNA interference (RNAi), and RNA aptamers. Of the four types, mRNA-based therapy is the only type which is based on triggering synthesis of proteins within cells, making it particularly useful in vaccine development. [ 3 ]

  5. RNA virus - Wikipedia

    en.wikipedia.org/wiki/RNA_virus

    Retroviruses (Group VI) have a single-stranded RNA genome but, in general, are not considered RNA viruses because they use DNA intermediates to replicate. Reverse transcriptase , a viral enzyme that comes from the virus itself after it is uncoated, converts the viral RNA into a complementary strand of DNA, which is copied to produce a double ...

    The Centers for Disease Control and Prevention (CDC) updated its RSV vaccine guidance for seniors for this upcoming respiratory viral season, saying the new recommendations are meant to simplify ...

  7. mRNA vaccine - Wikipedia

    en.wikipedia.org/wiki/MRNA_vaccine

    Retrovirus can be single-stranded RNA (just as many SARS-CoV-2 vaccines are single-stranded RNA) which enters the cell nucleus and uses reverse transcriptase to make DNA from the RNA in the cell nucleus. A retrovirus has mechanisms to be imported into the nucleus, but other mRNA (such as the vaccine) lack these mechanisms.

  8. DNA vaccine - Wikipedia

    en.wikipedia.org/wiki/DNA_vaccine

    Conventional vaccines contain either specific antigens from a pathogen, or attenuated viruses which stimulate an immune response in the vaccinated organism. DNA vaccines are members of the genetic vaccines, because they contain a genetic information (DNA or RNA) that codes for the cellular production (protein biosynthesis) of an antigen.
