What Is mRNA? Here’s A Crash Course On What It Does
网页2021年4月19日 · One surprising star of the coronavirus pandemic response has been the molecule called mRNA. It’s the key ingredient in the Pfizer and Moderna COVID-19 vaccines. But mRNA itself is not a new...
Messenger RNA - Wikipedia
网页In molecular biology, messenger ribonucleic acid (mRNA) is a single-stranded molecule of RNA that corresponds to the genetic sequence of a gene, and is read by a ribosome in the process of synthesizing a protein.
Messenger RNA (mRNA) | Description & Function | Britannica
网页4 天之前 · Messenger RNA, molecule in cells that carries codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm (the ribosomes). Each mRNA molecule encodes information for one protein. In the cytoplasm, mRNA molecules are translated for protein synthesis by the rRNA of ribosomes.
mRNA Vaccines: What They Are & How They Work - Cleveland Clinic
网页An mRNA vaccine works by triggering your immune system to create antibodies. Antibodies are proteins in the body. They fight bacteria and viruses that cause disease. The COVID-19 mRNA vaccines are safe and effective to prevent serious complications.
mRNA Technology: What It Is and How It Works - Pfizer
网页mRNA—or messenger RNA—is a molecule that contains the instructions or recipe that directs the cells to make a protein using its natural machinery. To enter cells smoothly, mRNA travels within a protective bubble called a Lipid Nanoparticle.
FDA Approves and Authorizes Updated mRNA COVID-19 …

Understanding COVID-19 mRNA Vaccines - National Human …
网页2021年8月30日 · Understanding COVID-19 mRNA Vaccines. Messenger RNA (mRNA) is a molecule that encodes a sequence that can be made into a protein. Scientists first learned about mRNA nearly 60 years ago, and researchers have been studying vaccines using mRNA for decades.
What are mRNA vaccines and how do they work? - MedlinePlus
网页mRNA vaccines work by introducing a piece of mRNA that corresponds to a viral protein, usually a small piece of a protein found on the virus’s outer membrane. (Individuals who get an mRNA vaccine are not exposed to the virus, nor can they become infected with the virus by the vaccine.)
What’s Different About Messenger RNA (mRNA) Vaccines for …
网页Messenger RNA (mRNA) vaccines, like the Pfizer and Moderna COVID-19 vaccines, teach cells how to make a protein that triggers an immune response if someone gets infected.
mRNA vaccines and immunity - Mayo Clinic
网页2021年2月10日 · mRNA is like a little recipe for how to make that spike protein. When we get these vaccines, our body makes that spike protein and we develop an immune defense to it without ever having to be exposed to the whole virus. It's not exposing us to the whole virus at all, live or killed.
