Microtubules in yeast cells - source of electromagnetic activity in the M phase of the cell cycle
Pokorný, Jiří ; Hašek, Jiří ; Jelínek, František
Electromagnetic activity was measured around cells of cold sensitivite tubulin mutants of Saccharomyces cerevisiae which displayed microtubules. Electromagnetic activity in the frequency range 8-9MHz coincides with evolution of the microtubular structures.
Electromagnetic field around yeast cells
Pokorný, Jiří ; Jelínek, František ; Šaroch, Jaroslav ; Hašek, Jiří ; Palán, B.
Electromagnetic field around synchronized cells of tubulin mutant tub2-401 of Saccharomyces cerevisiae was measured in the M phase of the cell cycle in the frequency range of 8-9 MHz. The measured electromagnetic activity is compared with the evolution of the mitotic spindle. The peaks of the electromagnetic activity seems to coincide with formation of the mitotic spindle, with binding of chromatids to kinetochore microtubules, with anaphase A, and with anaphase B.
Cavity modes of microtubules and biological cells in X-ray and infrared region
Jelínek, František ; Pokorný, Jiří
The microtubules in the cellular cytoskeleton have fundamental role in living processes of biological cells. They are hollow cylinders which resemble circular waveguides. The cutoff frequencies of the TM and TE modes of the microtubule cavities are in the band of the soft X-rays. This suggests the possibility of interaction of electromagnetic cavity modes with inner electrons in atoms. In the case of biological cells as cavity resonators the resonant frequencies may be in the infrared region.
