Linear sequences of nucleotides, in which the 5\'-linked phosphate on one sugar group is linked to the 3\' position on the adjacent sugars. In the polynucleotide DNA the sugar is deoxyribose and in RNA, ribose. They may be double-stranded or single-stranded with varying amounts of internal folding.
