WebDNA, short for deoxyribonucleic acid, is the molecule that contains the genetic code of organisms. This includes animals, plants, protists, archaea and bacteria. It is made up of two polynucleotide chains in a double helix. [1] DNA is in each cell in the organism and tells cells what proteins to make. Mostly, these proteins are enzymes. WebThe majority of the DNA is composed of G and C nucleotides, but the DNA still contains many A and T nucleotides. These results likely indicate that along with increasing GC pairing in the wobble position, thermophilic archaea have other mechanisms for stabilizing their DNA at such high temperatures.
