NUCLEAR GENOME SIZE AND CELL SIZE IN ANIMALS: MECHANISMS OF DIFFERENTIATION, PHYSIOLOGICAL AND ECOLOGICAL CONSEQUENCES

Nuclear genome size differs thousands-fold in animals and does not correlate with their com- plexity. Such pattern results from domination of non-coding, most often repetitive sequences in genomes. Most common types of repetitive sequences and their origin are mentioned. Then, some hypotheses on the origin of so great variability in the amount of non-coding DNA are presented. According to the present state of knowledge, a cause-and-effect chain exists, from the amount of DNA, through nucleus volume, to cell size.
