Ribonucleic acid; a type of genetic material. Humans, plants, animals, bacteria and some viruses have both DNA and RNA. In humans, DNA stores the information that says how to code our body, while RNA reads that DNA and helps make the proteins and enzymes that make things happen. Sometimes, the RNA can make things happen on its own, too. Coronavirus is an RNA virus or ribovirus, which means that drugs that treat it need to somehow block the virus’ RNA from invading our cells.
