mRNA, or messenger RNA, is a molecule that carries genetic information from DNA to the ribosome, where it is used to direct the synthesis of proteins. Research in the field of mRNA typically focuses on understanding its structure, function, and regulation, as well as developing technologies for manipulating mRNA expression levels. This includes studying mechanisms of mRNA transcription, processing, and translation, as well as the roles of mRNA in health and disease. Recently, mRNA has gained attention in the development of vaccines and therapeutics, such as mRNA vaccines for COVID-19.
