RNA and its molecular cousin DNA are nucleic acids that carry the genetic code. RNA, or ribonucleic acid, acts as an intermediate messenger for genes, the unit of inheritance carried in DNA.

RNA has played a starring role in vaccine technology helping to end the Covid-19 pandemic and save lives. Two Covid vaccines use messenger RNA to cause cells to produce a protein that stimulates the production of antibodies. Then you can destroy the actual coronavirus if it attacks your body.
