• Polycentric chromosomes are produced by chromosomal aberrations such as deletion, duplication, or translocation. (wikipedia.org)
  • Since the early years of radiobiology the cellular effects of ionizing radiation have been studied in the context of induced chromosomal aberrations, and early models of radiation action were largely based upon such studies (Savage 1996). (nationalacademies.org)
  • Polycentric chromosomes are produced by chromosomal aberrations such as deletion, duplication, or translocation. (wikipedia.org)
  • The blood samples of five healthy volunteers were irradiated with gamma ray, and each sample was divided equally for analysis of chromosomal aberrations by Giemsa staining and three-color fluorescence in situ hybridization painting of the triplet (chromosomes #1, #2, and #4). (bvsalud.org)
  • The results of chromosomal aberrations followed the Poisson distribution in all individual and averaged data which include inter-individual variation in radiation susceptibility. (bvsalud.org)
  • The specific role of histone H3 is that inclusion of one of its variants (the one designated as CENP-A in animals and as CENH3 (centromere-specific histone H3) in plants) in the nucleosomes defines the location of centromeres on chromosomes [ 3 ] and is essential for centromere and kinetochore formation in most organisms [ 4 ].
