[Liquid crystals and liquid crystal dispersions of DNA-daunomycin complexes].

The X-ray and optical properties as well as the textures of liquid crystals formed of DNA molecules bound in complex with an anthracycline antibiotic daunomycin were investigated. It was shown that DNA.daunomycin complexes, depending on the extent of alteration of the DNA secondary structure by daunomycin, could yield two types of cholesterics differing in the direction of their spatial twisting as well as nematics.

Cytogenetic investigation of Triticum timopheevii (Zhuk.) Zhuk. and related species using the C-banding technique.

Triticum timopheevii and related species T. militinae (2n=28, A(t)G) and T. zhukovskyi (2n=42, A(m)A(t)G), hybrids T.

General features of chromosome substitutions in Triticum aestivum x T. timopheevii hybrids.

Based on a C-banded chromosome analysis of Triticum aestivum x T. timopheevii hybrid lines, we developed a classification of the A(t) and G genome chromosomes that agrees with the standard genetic nomenclature of T. aestivum chromosomes.
