Comparisons of behavior of chromosomes and characteristics of eliminated chromatin during anaphase of chromatin diminution divisions were made of Russian and German populations of Cyclops kolensis and Cyclops strenuus strenuus. Differences in cytogen

The percentage and the size distribution of weakly divergent sites of repetitive sequences of human chromosomal DNA were determined in health and in hereditary genome diseases which are characterized by chromosome instability and predisposition to ma

The size of genomes in eukaryotic organisms is one of the greatest mysteries of biology. As known from the middle of the XX century, the level of organization of a particular organism, does not depend on its genome size, i. e. on DNA amount in the nu

The frequency of the chromosomes aberrations (FA) of Cyclops kolensis before chromatin diminution (CD), which were inducted by gamma-irradiation in 50 times exceeds the FA of Cyclops kolensis after CD, during the CD, reducing the genome of C. kolensi

The absence of progress in understanding the problem of redundant eukaryotic DNA is stated. This is caused primarily by the attempts to solve this problem either in terms of the traditional approaches (the general phenotypic parameters such as develo

The functions of redundant (junk, selfish, parasitic, etc.) DNA in eukaryotes can be reliably inferred from chromatin diminution (programmed elimination of up to 94% of the genome from somatic germ cells in Ascaris and Cyclops). These functions shoul

Chromosomal radiosensitivity inferred from the yield of chromosome aberrations (CAs) was for the first time studied in Cyclops (Crustacea, Copepoda) before and after chromatin diminution (CD). A comparison was made for C. kolensis, in which CD denude

General properties of aging in animals are considered on the basis of the literature evidence and the results obtained by the authors of this paper. The existence of a specific aging mechanism is inferred. The operation of this mechanism is controlle

We studied lifespan (LS) of Drosophila melanogaster strains HA and BA. The first one was generated by long-term selection for low male sexual activity and features decreased LS as well as the changes in a relatively constant index--coefficient of LS
