Scientists continue to study the structure of humanorganism in order to increase the effectiveness of the fight against incurable diseases. The unexpected conclusion was reached by the specialists of the Chalmers University of Technology (Sweden), who declared fundamental errors in the generally accepted theory of the structure of DNA (deoxyribonucleic acid).
The traditional theory is based on the statement aboutthat the main connecting element in the structure of DNA is hydrogen. The cyclic structure of DNA is built from blocks, which include a nitrogenous base, sugar and a phosphate group. The chains of the DNA molecule are directed by nitrogenous bases to each other and at the same time are connected by hydrogen bonds. However, the theory proposed by Swedish scientists is based on the assertion that DNA molecules are held by water, which is the basis of deoxyribonucleic acid chains.
New studies have shown that the environment,the surrounding DNA is hydrophilic, while the DNA molecules themselves have a hydrophobic structure. Therefore, to reduce the effect of water, hydrophobic DNA molecules are grouped together. Hydrogen bonds, which, according to the traditional theory, were the basis for the retention of chains of spirals, are most likely necessary for sorting pairs of nitrogenous bases.
The confirmation of a new theory can fundamentally changevision of the process of interaction of DNA with the environment, including the increase in the effectiveness of the fight against bacteria and oncological diseases. Studying the process of recovering DNA molecules will help in the process of understanding the principles of the origin of malignant tumors, the researchers say.
