single-stranded nucleic acid


single-stranded nucleic acid
Nucleic acid molecules consisting of only one polynucleotide chain. The genomes of many viruses are single-stranded DNA molecules, as are most biologically effective RNAs. Many RNA molecules do include double-stranded regions formed by the intra-strand base-pairing of self-complementary sequences, and these determine the 3-dimensional shape (conformation) that they adopt in vivo.
