RNA technology involves the use of ribonucleic acid (RNA) molecules to develop new treatments and vaccines. It plays a crucial role in gene expression, where RNA helps translate genetic information from DNA into proteins. This technology has gained significant attention for its potential in combating diseases, including viral infections and genetic disorders. One of the most notable applications of RNA technology is the development of mRNA vaccines, such as those used for COVID-19. These vaccines use synthetic messenger RNA to instruct cells to produce a harmless piece of the virus, prompting an immune response without causing the disease.
