Abstract:

Hidden symmetries in long sequences of oligonucleotides of single stranded DNA from their representative set are described. These symmetries are an addition to symmetries described by the second Chargaff’s parity rule (%A ≅ %T and %G ≅ %C). These new symmetries and their rules concern collective probabilities of oligonucleotides from special tetra-alphabetical sets in long DNA-texts including all chromosomes of human and some model organisms [1]. These rules of tetra-alphabetical probabilities are considered as candidacies for the role of universal rules of long DNA-sequences. On the basis of the known quantum-mechanic statement that quantum state of a multi-component system is defined by the tensor product of quantum states of its subsystems, a quantum-information model of genetic symmetries of these collective probabilities was proposed. In this model, nitrogenous bases C, T, G, A of DNA were represented as computational basis states of 2-qubit quantum systems [1]. The biological meaning of the new quantum-information symmetries of long DNA-texts can be connected with the common ability of organisms to grow on the basis of incorporation into their body of new molecules of nutrients becoming new quantum-mechanic subsystems of the united quantummechanical organism.
