  2. 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.

  3. Self-amplifying RNA - Wikipedia

    en.wikipedia.org/wiki/Self-amplifying_RNA

    Self-amplifying RNA (saRNA), also termed self-replicating RNA (srRNA), is a type of mRNA molecule engineered to replicate itself within host cells, enhancing protein expression and boosting the immune response, making it a promising tool for vaccines and other therapeutic applications. As a "next-generation" mRNA, saRNA is designed to achieve ...

  4. mRNA-4157/V940 - Wikipedia

    en.wikipedia.org/wiki/MRNA-4157/V940

    mRNA-4157/V940 is an mRNA based cancer vaccine. When administered, it will produce one of several dozen possible abnormal proteins commonly found in cancerous tissues. The production of those proteins is intended to invoke an immune response. mRNA-4157/V940 is given to patients after their tumors have been sequenced and abnormal proteins ...

    en.wikipedia.org/wiki/Messenger_RNA

    A 5' cap (also termed an RNA cap, an RNA 7-methylguanosine cap, or an RNA m 7 G cap) is a modified guanine nucleotide that has been added to the "front" or 5' end of a eukaryotic messenger RNA shortly after the start of transcription. The 5' cap consists of a terminal 7-methylguanosine residue that is linked through a 5'-5'-triphosphate bond to ...

  9. Nucleoside-modified messenger RNA - Wikipedia

    en.wikipedia.org/wiki/Nucleoside-modified...

    A nucleoside-modified messenger RNA (modRNA) is a synthetic messenger RNA (mRNA) in which some nucleosides are replaced by other naturally modified nucleosides or by synthetic nucleoside analogues. [ 1 ] modRNA is used to induce the production of a desired protein in certain cells.
