摘要: Mammalian interphase nuclei are highly organized structures in which chromosome territories nonrandomly distributed following a radial pattern. Gene richness and size markedly influence nuclear positioning. Active euchromatin inactive heterochromatin exhibit different topology: the former is centrally located latter mostly placed at periphery, within chromocenters, around nucleoli. DNA subjected to wide repertoire of insults including radiation, chemical, biological agents. The differential sensitivity clastogens has been matter debate, although most experimental evidence supports that more damage prone. expression synthesis coupled chromatin remodeling could act as key factors distribution aberrations (CA) euchromatic heterochromatic regions genome. In this chapter, main features architecture well an overview current knowledge genetic metaphase levels presented. Also, preferential involvement transcriptionally active human genome regarding induction deregulation tumor genes analyzed. Finally, impact replication timing connected processes generation localization CA primary discussed.
