13. In metaphase, Chromatid fragments are attached to the homologous area of the sister Chromatid while acentric chromosome fragments are apart from their chromosome of origin.

14. There were chromatid type aberrations including gaps and breaks of one or both chromatids and chromosome type aberrations such as acentric fragments dicentis, rings and other abnormal chromosomes.

15. Many X-ray or chemical mutagen-induced chromosome translocations in domestic fowl (Gallus domesticus) are thought to involve microchromosomes as centromere donors to acentric macrochromosomal fragments.

16. However, a chromatin bridge and acentric fragment were recorded in certain hybrid combinations, suggesting that the evolutionary divergence in genomically similar species occurred because of paracentric inversions.

17. Micronuclei may originate from acentric chromosome fragments (i.e. lacking a centromere), or whole chromosomes that are unable to migrate to the poles during the anaphase stage of cell division.

18. Breakage of chromatids or chromosomes can result in micronucleus formation if an acentric fragment is produced; therefore assays detecting either chromosomal aberrations or micronuclei are acceptable for detecting clastogens (see note 5).

19. In a fruit fly model system (Drosophila larva) in which acentric chromosomes (without centromeres) were induced, chromosomes still tethered to the spindle and segregated to the poles, and adult survival was not impaired.

20. Translocations of acentric fragments to the long arms of X chromosomes and fusions of deleted X chromosomes resulting in dicentric chromosomes were also observed, but no translocations to euchromatic chromosomes could be found.

21. The length of the chromatid arms of acentric chromosomes is transiently increased during mitosis, putting them at risk of essentially being chopped during cleavage of the cytosol in the final step of mitosis.

22. The cytogenetic findings in leucocytes as well as fibroblast cultures indicated that the small acentric chromosome fragment found in approximately half of the cells was made up of the short arms of a Y chromosome.

23. Bridge plus acentric fragment configurations involving 4AL and 4AtL were identified in cells at anaphase I. This result suggests that the paracentric inversion of 4AL from T. turgidum does not exist in T. timopheevii.

24. However, crossing-over in the paired interstitial region may greatly increase segregational load as result of multivalent formation at metaphase one (MI) and the generation of dicentric bridge(s) and acentric fragment(s) upon cell division.

25. The parameters “percentage of dicentric chromosomes”, “breaks”, and “excess acentric fragments” in comparison to the total number of mitoses analyzed could neither serve as meaningful nor as significant criteria, since they showed a strong interindividual variability.

26. It is shown that the crystal structure of the autunite group mineral threadgoldite, Al(UO2)2(PO4)2(OH)·8H2O, recently determined byPiret et al. (1979) in the acentric space groupCc, can be better described and refined in the centrosymmetric space groupC2/c.

27. The high portion of metaphases with aberrations of chromosomes is especially noted. Among the aberrations of chromosomes breaks of chromosomes and chromatids were especially frequent. Rarefactions, achromasia and entspiralisation were not so frequent. There were still less acentric fragments and dicentric chromosomes.

28. The detailed analysis was focused on the number of breaks per metaphase, on breaks from complex chromosomal rearrangements per metaphase, as well as on the percentage of translocations, dicentric chromosomes, breaks, and excess acentric fragments—each in comparison with the total number of mitoses analyzed.

29. Concentric: 1 adj having a common center “ Concentric rings” Synonyms: Concentrical , homocentric coaxal , coaxial having a common axis Antonyms: eccentric , nonConcentric not having a common center; not Concentric acentric not centered or having no center off-center , off-centered situated away from the center or axis show more antonyms

30. Meiosis in hybrids derived from crosses of Secale ancestrale Zhuk. with related species is highly irregular: chiasmata fail to terminalize; numerous AI and AII bridges form but are usually unaccompanied by fragments; acentric fragments without true bridges are left behind at AI and AII; numerous micronuclei are produced at TII.

31. The plate pack (2) of the heat exchanger is arranged inside the shell (3) in an acentric manner, so that the midpoint of the cross-section of the plate pack (2) deviates substantially from the midpoint of the cross-section of the shell (3) in the vertical direction and/or lateral direction of the cross-section.

32. genetic toxicity, genotoxicity: a broad term that refers to any deleterious change in the genetic material regardless of the mechanism by which the change is induced. micronucleus: particle in a cell that contains microscopically detectable nuclear DNA; it might contain a whole chromosome(s) or a broken centric or acentric part(s) of chromosome(s).

33. DNA-repair, DNA-adduct formation, etc.) genetic toxicity, genotoxicity: a broad term that refers to any deleterious change in the genetic material regardless of the mechanism by which the change is induced. micronucleus: particle in a cell that contains microscopically detectable nuclear DNA; it might contain a whole chromosome(s) or a broken centric or acentric part(s) of chromosome(s).

34. The irradiation of the blood at an intensity of 3 W/cm2 and a frequency of 810 kHz for the duration of 10 min showed no change in the total number of breaks as against the controls; the slight increase in the number of dicentrics and rings was balanced approximately by an equal decrease in the number of acentric fragments.

35. One in vivo study exposed rats (strain unspecified, route probably inhalation) to hydrogen sulphide or carbon disulphide for three to four months, inducing chromosomal aberrations (aneuploidy, deletions, acentric fragmentation) in the bone marrow of the adult rats and decreasing the mitotic index in the kidney and liver cells of developing embryos.(63) In a reproduction study, hydrogen sulphide was reported to be embryotoxic and to have an adverse effect upon reproductive function in rats.
