Genetic mechanisms of formation of radiation-induced instability of the genome and its transgenerational effects in the descendants of chronically irradiated individuals of Drosophila melanogaster.

abstract：:Native horseradish peroxidase, as well as its reduced and carboxymethylated form, and the apoenzyme, showed resistance to photodynamic action. Sensitivity to this action was detected only in reduced and carboxymethylated apoenzyme, when the photooxidation of its histidine residues was observed. When analyzing the bulk...
