The nucleic acid notation currently in use was first formalized by the International Union of Pure and Applied Chemistry (IUPAC) in 1970. [1] This universally accepted notation uses the Roman characters G, C, A, and T, to represent the four nucleotides commonly found in deoxyribonucleic acids (DNA).
Nucleic acids RNA (left) and DNA (right). Nucleic acids are large biomolecules that are crucial in all cells and viruses. [1] They are composed of nucleotides, which are the monomer components: a 5-carbon sugar, a phosphate group and a nitrogenous base. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid ...
Nucleic acid structure refers to the structure of nucleic acids such as DNA and RNA. Chemically speaking, DNA and RNA are very similar. Chemically speaking, DNA and RNA are very similar. Nucleic acid structure is often divided into four different levels: primary, secondary, tertiary, and quaternary.
This is the standard genetic code (NCBI table 1), in amino acid→codon form. By default it is the DNA code; for the RNA code (using Uracil rather than Thymine), add template parameter "T=U". Also listed are the compressed codon forme, using IUPAC nucleic acid notation. It's referenced in a couple of places, so have a single master copy.
A DNA code is simply a set of sequences over the alphabet = {,,,}.. Each purine base is the Watson-Crick complement of a unique pyrimidine base (and vice versa) – adenine and thymine form a complementary pair, as do guanine and cytosine.
The sequence of nucleobases on a nucleic acid strand is translated by cell machinery into a sequence of amino acids making up a protein strand. Each group of three bases, called a codon, corresponds to a single amino acid, and there is a specific genetic code by which each possible combination of three bases corresponds to a specific amino acid.
Nucleic acids are complex, high-molecular-weight biochemical macromolecules composed of nucleotide chains. The main article for this category is Nucleic acids . Wikimedia Commons has media related to Nucleic acids .
It is not always the case that the structure of a molecule is easy to relate to its function. What makes the structure of DNA so obviously related to its function was described modestly at the end of the article: "It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material".
