and are often embedded in heterochromatic regions. In most eukaryotes, ribosomal genes,
as well as centromeres and telomeres or subtelomeres, are associated with abundant
tandem arrays of repetitive sequences and typically represent the final barriers to completion
of whole-genome sequencing. The nature of these repeats makes it difficult to estimate their
actual sizes. In this study, combining the two cytological techniques DNA fiber-FISH and …
