- RNA stands for ribonucleic acid, which is a long, single-stranded chain of cells that processes protein.
An example of RNA is a chain of cells that carries genetic information of many viruses from the cell to the cytoplasm.
a nucleic acid that is an essential component of all cells, composed of a long, usually single-stranded chain of nucleotide units that contain the sugar ribose; ribonucleic acid
A nucleic acid present in all living cells and many viruses, consisting of a long, usually single-stranded chain of alternating phosphate and ribose units, with one of the bases adenine, guanine, cytosine, or uracil bonded to each ribose molecule. RNA molecules are involved in protein synthesis and sometimes in the transmission of genetic information. Also called ribonucleic acid.
