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 ...
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 ...
In addition, Meselson, François Jacob, and Sydney Brenner discovered the existence of messenger RNA in 1961. Meselson has investigated DNA repair in cells and how cells recognize and destroy foreign DNA, and, with Werner Arber, was responsible for the discovery of restriction enzymes.
RNA editing was first discovered within the mitochondria of kinetoplastid protozoans, where it has been shown to be extensive. [30] For example, some protein-coding genes encode fewer than 50% of the nucleotides found within the mature, translated mRNA. Other RNA editing events are found in mammals, plants, bacteria and viruses.
Monica Riley (1926 – October 11, 2013) was an American scientist who contributed to the discovery of messenger RNA in her Ph.D work with Arthur Pardee, and was later a pioneer in the exploration and computer representation of the Escherichia coli genome.
Howard Haym Hiatt (July 22, 1925 – March 2, 2024) was an American medical researcher involved with the discovery of messenger RNA.He was the onetime chair of the department of medicine at Beth Israel Hospital in Boston from 1963 to 1972.
The first use of RNA for vaccination purposes was described in 1993 by Frédéric Martinon, Pierre Meulien and colleagues [10] [11] and in 1994 by X. Zhou, Peter Liljeström, and colleagues in mice. [12] [11] Martinon demonstrated that a cellular immune response was induced by vaccination with an RNA vaccine. [11]
Phillip Allen Sharp (born June 6, 1944) is an American geneticist and molecular biologist who co-discovered RNA splicing.He shared the 1993 Nobel Prize in Physiology or Medicine with Richard J. Roberts for "the discovery that genes in eukaryotes are not contiguous strings but contain introns, and that the splicing of messenger RNA to delete those introns can occur in different ways, yielding ...
