Transfer of genetic information in an organism.

New knowledge in biology led us to a better understanding of organization and functioning of living organisms. Today, re-evaluation of our concept of human biology is taking place. Theoretical analysis shows that taking into account the complexity of the organism and frequency of spontaneous mutations, it is impossible to explain the real time of organismal life.

[The purification of beta-galactosidase by flow electrophoresis].

A plant has been constructed for the free-flow electrophoresis. It permits carrying out electrophoretic separation both in a free flow and with the use of neutral grained fillers. Beta-galactosidase has been purified from the culture liquid of the Escherichia coli cell phage lysate.

[Light microscopic and electron microscopic study of the cells of tissue cultures irradiated with a neodymium laser].

Damage of tissue culture cells (Hela, a human amnion, a primary rat liver culture) caused by the neodymium laser radiation was studied by time-lapse phase-contrast microfilming and electron microscopy. The tested cultures were shown to display different sensitivity and the degree of cell alteration within the same cultures varied considerably. A physical mechanism of cell damage is probably of thermal and shock-wave nature.
