[Genetic analysis of the South Altaian population of the Mendur-Sokkon village, Altai Republic].

This study was a continuation of complex research on the gene pool of indigenous Siberian populations conducted at the Institute of Cytology and Genetics, Siberian Division, Russian Academy of Sciences. In the population of South Altaians from the Mendur-Sokkon village, Ust'-Kanskii raion, Altai Republic, polymorphism for the following genetic markers was studied: blood groups ABO, MNSs, Rhesus, Kell, Duffy, and P; erythrocyte acid phosphatase (AcP); phosphoglucomutase 1 (PGM1); haptoglobin (Hp); and transferrin (Tf). The genetic position of South Altaians relative to the populations of the European part of Russia, Siberia, and the Urals was estimated.

[Increased content of nucleotide sequences in transcriptionally active DNA and poly(A)+-mRNA of the rat liver and a rise in its translation activity as affected by inducers].

Cortisol and 3'-methyl-4-dimethyl-amino-azobenzene induce an increase in the content of repeated sequences (RS) in transcriptionally active (TA) DNA, while the content of respective RS in potentially active DNA fractions enriched with regulatory regions of the genome decreases. RS content in induced poly A+-mRNA also rises, as determined by the nature of hybridization of respective c DNA with total DNA. The translation of induced poly A+-mRNA rises essentially, with the qualitative distinctions in in vitro synthesized protein product spectrum being absent.
