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.

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...

An mRNA vaccine is a preventive treatment that helps your body learn to fight diseases. A healthcare provider gives you the vaccine in a shot or series of shots.

2025年3月26日 · Messenger RNA (mRNA) is a 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.

An mRNA vaccine is a type of vaccine that uses a copy of a molecule called messenger RNA (mRNA) to produce an immune response. [1] The vaccine delivers molecules of antigen -encoding mRNA into cells, which use the designed mRNA as a blueprint to build foreign protein that would normally be produced by a pathogen (such as a virus) or by a cancer ...

3 天之前 · Messenger RNA (abbreviated mRNA) is a type of single-stranded RNA involved in protein synthesis. mRNA is made from a DNA template during the process of transcription.

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.

mRNA vaccines use a piece of mRNA that corresponds to a protein on a virus. Vaccines for COVID-19 are the only mRNA vaccines authorized or approved by the FDA.

2017年4月28日 · Messenger ribonucleic acids (mRNAs) transfer the information from DNA to the cell machinery that makes proteins. Tightly packed into every cell nucleus, which measures just 10 microns in diameter, is a three-meter long double-stranded DNA “instruction manual” on how to build and maintain a human body.

2023年8月3日 · mRNA is also known as messenger RNA, is a type of RNA molecule that carries the code from the DNA in the nucleus to the site of protein synthesis in the cytoplasm, ribosome.
