Record number: 1, Textual support number: 1 DEF

A broken-off piece of a chromosome that lacks centromere and therefore its distribution to the poles during nuclear divisions is random and commonly it is lost.  1, record 1, English, - acentric%20fragment

Record number: 1, Textual support number: 1 OBS

Acentric fragments are frequent consequences of irradiation of cells with X rays and other ionizing radiations. Chromosomal inversions may generate bridges (shown between the two poles) and three acentric chromosome fragments of substantial size that are drifting in the middle of the cell and are not distributed to the poles.  1, record 1, English, - acentric%20fragment

Le fragment acentrique ne se déplace pas au cours de l'anaphase puisqu'il ne possède pas de point d’attache et ne peut donc s’ancrer à l'une des fibres du fuseau; il se perd dans le cytoplasme après la formation de la nouvelle enveloppe nucléaire. Dans les deux chromosomes recombinés, il y ainsi des délétions et aussi de temps en temps, des duplications et par conséquent, les zygotes qui en résultent ne sont pas viables.  1, record 1, French, - fragment%20acentrique

A deletion resulting in the formation of an acentric and a centric fragment of chromosome.  1, record 2, English, - terminal%20deletion

Record number: 2, Textual support number: 1 CONT

(Autosomal structural rearrangements). A good example of this is the deleted B group chromosome resulting in the cri du chat. This could arise by at least four different mechanisms which are terminal deletion, interstitial deletion, translocation, and unequal chromatid intrachange, and there are at least eight families in which the mechanism has been shown to be a reciprocal translocation.  1, record 2, English, - terminal%20deletion

Délétion aboutissant à la formation d’un fragment acentrique et d’un fragment centrique de chromosome.  1, record 2, French, - d%C3%A9l%C3%A9tion%20terminale

(Modifications intra-chromosomiques). Il arrive qu’après une cassure, un fragment de chromosome soit éliminé, il en résulte un raccourcissement d’un bras chromosomique. Cette délétion peut être terminale ou intercalaire.  1, record 2, French, - d%C3%A9l%C3%A9tion%20terminale
