About this work


Human chromosomes at metaphase, highlighted by fluorescent probes that bind to specific sequences of DNA. Patient with Turner's syndrome and a 45,X/46,Xr(X) mosaic karyotype. The X centromere probe (green) shows that the small ring chromosome is of X origin and the XIST cosmid (red) shows that XIST is not deleted in the r(X). (See also B0000320C) Image by Dr John Crolla.
