RNA has various meanings in the Medical category. Discover the full forms, definitions, and usage contexts of RNA in Medical.
Ribonucleic acid is a polymeric molecule. It is implicated in various biological roles in coding, decoding, regulation, and expression of genes. DNA and RNA are nucleic acids, and, along with proteins and carbohydrates, constitute the three major macromolecules essential for all known forms of life. Like DNA, RNA is assembled as a chain of nucleotides, but unlike DNA it is more often found in nature as a single-strand folded unto itself, rather than a paired double-strand.
