deoxyribonucleic acid (dna) and ribonucleic acid (rna) are of great importance because they code for the production of all cellular proteins. they are made up of monomers called nucleotides which consist of an organic base: a, g, c and t or u, a pentose sugar, and a phosphate group. they have backbones in which the 3’ carbon of the ribose sugar is connected to the phosphate group via a phosphodiester bond. this bond is formed through with the help of a class of cellular enzymes called polymerases. in this enzymatically driven condensation reaction, all incoming nucleotides have a triphosphorylated ribose which loses a pyrophosphate group to form the inherent phosphodiester bond. this reaction is driven by the large negative free energy change associated with the release of pyrophosphate. the sequence of bases in the nucleic acid backbone is also known as the primary structure. nucleic acids can be millions of nucleotides long thus leading to the genetic diversity of life. the bases stick out from the pentose-phosphate polymer backbone in dna and are hydrogen bonded in pairs to their complementary partners (a with t and g with c). this creates a double helix with pentose phosphate backbones on either side, thus forming a secondary structure.

nucleic acid secondary structure









































nucleic acid secondary structure is the basepairing interactions within a single nucleic acid polymer or between two polymers. it can be represented as a list of bases which are paired in a nucleic acid molecule.









































the secondary structures of biological dna's and rna's tend to be different: biological dna mostly exists as fully base paired double helices, while biological rna is single stranded and often forms complex and intricate base-pairing interactions due to its increased ability to form hydrogen bonds stemming from the extra hydroxyl group in the ribose sugar.
