ribonucleic acid (rna) – ribonucleic acid: any of a class of single-stranded molecules transcribed from dna in the cell nucleus or in the mitochondrion or chloroplast, containing along the strand a linear sequence of nucleotide bases that is complementary to the dna strand from which it is transcribed: the composition of the rna molecule is identical with that of dna except for the substitution of.
ribose for deoxyribose and the substitution of the nucleotide base uracil for thymine.
