Rna

(Science: molecular biology) A nucleic acid found in all living cells. Plays a role in transferring information from dNA to the protein-forming system of the cell. (biochemistry) a long linear polymer of nucleotides found in the nucleus but mainly in the cytoplasm of a cell where it is associated with microsomes; it transmits genetic information from dna to the cytoplasm and controls certain chemical processes in the cell; ribonucleic acid is the genetic material of some viruses.A nucleic acid similar to that of dna, thought the deoxyribose acid is replaced with ribose sugar and all thymine bases are replaced with uracil. Rna is a vital component of protein synthesis as it is able to read the genetic blueprint found in dna to make.
