Definitions. Nucleic acids are polymers of nucleotides. In eukaryotic cells nucleic acids are either:. Deoxyribose nucleic acids (DNA). Ribose nucleic acids (RNA). Messenger RNA (mRNA). Transfer RNA (tRNA). Ribosomal RNA (tRNA). Nucleotides are carbon ring structures containing nitrogen linked to a
