[Regulation of multimeric structure of NO-synthase as a new factor of organogenesis].

The effect of NO on organogenesis in Drosophila is discussed. A new model of regulation of the activity of NO-producing enzyme, NO synthase is described, which takes into account endogenous synthesis of its reduced isoform. The reduced isoform of NO synthase is capable of suppressing the enzymatic activity of full-sized NO synthase during formation of a heterodimer in vivo and in vitro.

Experimental evidence for the binemic structure of human chromosomes.

A binemic model of eukaryotyc chromosome was tested using PCR-amplification of some unique genes in individual sperm cells or in human DNA diluted to 1/2 of the DNA amount of a haploid cell. According to the model, all the hereditary information, including all the unique genes, is represented twice in the haploid genome. Backing up of information enhances reliability of the genome by several orders of magnitude.
