Rearrangements and chromosomal evolution
Current Opinion in Genetics & Development, 2003Comparisons of the genome sequences of related species suggests varying patterns of chromosomal rearrangements in different evolutionary lineages. In this review, I focus on the quantitative characterization of rearrangement processes and discuss specific inventories that have been compiled to date.

Chromosome rearrangements in trypanosoma brucei
Cell, 1984We have studied chromosome rearrangements in T. brucei using pulsed field gradient gel electrophoresis to separate chromosome-sized DNA molecules. We detect size changes in a set of small chromosomes (200-700 kb) at a frequency of 10(-5) to 10(-6) per trypanosome division; this results in a radical difference in the size distribution of these ...

Chromosome Rearrangements and Transposable Elements
Annual Review of Genetics, 2002▪ Abstract There has been limited corroboration to date for McClintock's vision of gene regulation by transposable elements (TEs), although her proposition on the origin of species by TE-induced complex chromosome reorganizations in combination with gene mutations, i.e., the involvement of both factors in relatively sudden formations of species in ...

Structural Chromosome Rearrangements
1999The subject of structural chromosome rearrangements is an immense one, to which entire catalogs have been devoted. Indeed, there are theoretically an almost infinite number of ways in which chromosomes can reconfigure themselves from the normal 23-pair arrangement with which we are familiar.

X chromosome rearrangements usually convey clinical manifestations in the hemizygous males and are, thus, readily ascertained. They are found in all parts of the X chromosome and are associated with more than 20 disorders. Some of the rearrangements are the results of homologous recombination between low-copy repeats (LCRs) on the X chromosome or ...

Balanced Chromosome Rearrangements
2006Abstract Balanced chromosome rearrangements are those in which there is no overall loss or gain of chromosome material. Unlike single-gene disorders, for which precise calculation of risks to offspring is usually possible, the segregation of chromosome rearrangements does not readily conform to any mathematical model that permits exact ...

Chromosome rearrangements in Giardia lamblia
Parasitology Today, 1994Recent studies have shown that the genome of Giardia lamblia is plastic. Clinical isolates exhibit extensive karyotypic heterogeneity and chromosome rearrangements occur frequently, in vitro. In this review, Sylvie Le Blancq looks at genome organization and the impact of DNA rearrangement events.
