Balanced Chromosomal Rearrangement in Recurrent Spontaneous Abortions: A Case Report
One of the major causes of spontaneous abortion before the fourth month of pregnancy is chromosomal abnormalities. We report an unusual case of a familial balanced chromosomal translocation in a consanguineous couple who experienced 4 spontaneous abortions. Chromosomal studies were performed on the basis of G-banding technique at high resolution and revealed 46, XX, t (16 6) (p12 q26) and 46, X...
متن کاملChromosomal deletion and rearrangement in Streptomyces glaucescens.
The Streptomyces glaucescens genome frequently undergoes gross genomic rearrangement events which result in the deletion of extremely large segments of chromosomal DNA. The structure and origin of the DNA forming the novel junctions arising from five of these deletion events are described. Only one junction proved to be the result of a relatively simple event; the remainder were more complex, w...
متن کاملChromosomal Breakpoint Reuse in Genome Sequence Rearrangement
In order to apply gene-order rearrangement algorithms to the comparison of genome sequences, Pevzner and Tesler bypass gene finding and ortholog identification and use the order of homologous blocks of unannotated sequence as input. The method excludes blocks shorter than a threshold length. Here we investigate possible biases introduced by eliminating short blocks, focusing on the notion of br...

متن کاملChromosomal Mutation for Citrate Utilization
A mutant strain of Escherichia coli K-12 that utilizes citrate as a sole source of carbon and energy was isolated. Citrate utilization arose as the consequence of two mutations in genes citA and citB, which are linked to the gal operon. The mutant strain expresses a semiconstitutive citrate transport system, and it utilizes both citrate and isocitrate as carbon and energy sources. It is capable...
