In order to enhance the outcome of high-quality reverse transcriptase enzyme, an efficient biotechnology was developed of accumulating and isolating the avian myeloblastosis virus (AMV) in high titres from blood plasma of leukosis-free chickens. When

MC29 virus induces acute leukemia (myelocytomatosis) and primary tumors of liver (hepatomas) in turkey poults. By in vivo passages two viruses were selected; designated "liver" and "bone marrow" variants, differing in hepatoma-inducing activity. The

Mustine inhibits the template activity of chromatin and DNA in an RNA-polymerase system in vitro much more strongly than its monofunctional analogue. Chromatin is more sensitive to the action of mustine than is deproteinized DNA. However, the templat

By the use of various methods of deproteinization of chromatin (gel-filtration, ultracentrifugation, chromatography on calcium hydroxyapatite) the authors showed that by interaction between the chromatin and a bifunctional alkylating agent (embichin-

Embichin inhibited the matrix activity of chromatin and DNA in the RNA-polymerase system in vitro much more than its monofunctional analogue. Chromatin possessed a greater sensitivity to the action of embichin in comparison with the deproteinised DNA

The interaction of different preparations of chromatin non-histone proteins (NHP) isolated from rat liver and thymus with homologous and heterologous DNA was studied by a membrane filter technique. All the NHP preparations studied form complexes with
