To disclose the mechanism of "biological clock" approached by Japanese scientists. In experiments with blue-green algae, biologists from the University of Nagoya and Kyoto have found that the 24-hour circadian rhythm is established and governed by a special group of proteins.

In today published the results of studies have indicated that the basic processes of life cyanobacteria are subject to a 24-hour cycle. Control its three types of proteins.

Analyzing the structure of one of them, microbiologists have found that the protein consists of three sections. When exposed to a change in the internal rhythms. Experiments have shown that the deviation of the daily cycle of bacteria occurred during the middle of the block.

Similar effects on the end portion of the lead to the complete breakdown of rhythm. In this case, reproduction, and other important life processes of acquiring a random character.

Now scientists are trying to find out how the biological clock is tuned exactly to the 24-hour cycle. Its failure leads to various diseases.
