Spontaneous mutation of some genes was studied in haploid adenine and leucine auxotrophic yeast Saccharomyces. It was shown that a decrease in the amount of adenine (from 500 to 0 mgl−1) or leucine (from 300 to 0·3 mgl−1) in the medium, simultan

The possibility of amplifying molecular asymmetry by polymerization is investigated in some simple models. The results indicate that significant amplification may occur only temporarily, whereas for longer time periods the asymmetry vanishes or even

The frequency of reversion from adenine auxotrophy in yeasts grown on solid media increases in inverse proportion to the concentration of adenine in the medium. This correlation is observed at different periods of registration of the effect, although

Two simple models are presented in which a small difference in the reaction rates of the enantiomers results in a perfect optical purity. If racemization is also taken into account, the asymptotic state ceases to be absolutely asymmetric, nevertheles

A distinction is suggested between the notions ‘information tare’, the role of which is played by the signals or letters forming the message, and ‘information’, which may be contained in such messages. It is shown that Shannon's definition of

A complete theoretical system of double inhibitions has been evolved where the inhibitors may be purely or partially competitive, noncompetitive, or purely uncompetitive with the substrate. A method is presented for the determination of interaction c

A theory is presented concerning the possible arrangements of protomers in tetrameric molecules. Isoenzymes may exist even in the case of homotetramers if the asymmetry of the identical protomers is detectable. The number of tetrahedral isoenzymes th

Eq. (1) is used also in binding studies, with cb and cf (concentration of bound and free ligand) instead of Y and c, respectively. The two parameters, the maximal, asymptotic velocity (v) and the Michaelis constant (Km), have been traditionally evalu

The main types of models related to the origin of biological asymmetry are reviewed and new models are proposed. It is shown that in polymerization (in contrast to Yamagata's hypothesis) only a temporary amplification of asymmetry occurs. Models have
