Interaction of the HMG1 protein with nucleic acids

AbstractBinding constants have been measured for the interaction of the protein HMG1 with native DNA, denatured DNA and a number of polynucleotides at near-physiological ionic strengths, using gel filtration and thermal denaturation. The interaction of HMG1 with DNA is shown to be noncooperative and reversible. Nucleic acids form the following series in order of increasing binding constants: poly(U) ∞ poly(A) < poly(dA) < dsDNA ∞ poly(dA) · poly(dT) ∞ poly(dG) · poly(dC) « poly[d(A-T)] ∞ ssDNA

RUSSIAN-LANGUAGE DICTIONARIES AS A MEANS OF FORMATION OF BELARUSIAN STUDENT’S LANGUAGE CONSCIOUSNESS

The aim of the article is to represent the role of the Russian-language and encyclopedic dictionaries in teaching the Russian language in educational institutions of the Republic of Belarus. The material of the research is based on the lexicographical resources that contain linguistic and cultural information for revealing subject competence. The methods of the research are the following: a descriptive method, modeling the educational process and its elements. The main results of the research show the ways of revealing personally-oriented development as a model for providing students’ language, speech, communicative and cultural competence.
