Differences in human X isochromosomes.
In this paper we describe two types of i(Xq), in three patients. A classification is proposed for at least seven different types of human i(Xq)s or X long-arm duplications described by banding in the literature. Type 1 reported here and also in the literature may be the most common. It consists of a single visible centromere, metacentric, length similar to number 3, G-banding interpreted as i(X...
متن کاملIsochromosomes in Tomato.
HROMOSOMES with two similar ends have been recognized since the pioneer work of BELLING and BLAKESLEE (1924) on the secondary trisomes of Datura. More recently, the term, isochromosome, has been applied .by DARLINGTON (1939) to those chromosomes which have two identical arms. When found occurring naturally, the isochromosome has usually been shown to consist of inert, or B-type chromosomal mate...

15 صفحه اولDicentric breakage at telomere fusions.
Nonhomologous end-joining (NHEJ) inhibition at telomeres ensures that native chromosome ends do not fuse together. But the occurrence and consequences of rare telomere fusions are not well understood. It is notably unclear whether a telomere fusion could be processed to restore telomere ends. Here we address the behavior of individual dicentrics formed by telomere fusion in the yeast Saccharomy...
متن کاملDicentric Y chromosome in mixed gonadal dysgenesis.
A 15-year-old girl was investigated because of ambiguous genitalia. Her chromosome studies showed a 45, X/45, Xdic(Yq) mosaicism. The identity of the dicentric Y chromosome was demonstrated by its typical fluorescent banding patterns. Histological evidence of mixed gonadal dysgenesis with intragonadal tumour was observed, confirming the occurrence of gonadoblastoma associated with mosaicism in ...
