... Satellite DNA Tandem repeats Mitotic chromosomes are among the most recognizable structures in the cell, yet their internal organization remained largely unsolved for over a century. The pathway of mitotic chromosome formation has been identified only recently, with the help of imaging combined...

...Miluse Vozdova; Svatava Kubickova; Halina Cernohorska; Jan Fröhlich; Jiri Rubes Satellite DNA is a characteristic component of mammalian centromeric heterochromatin, and a comparative analysis of its evolutionary dynamics can be used for phylogenetic studies. We analysed satellite and satellite...

This study is aimed at developing cytogenetic markers for chromosome identification of wheat and Aegilops geniculata (2n = 4x = 28, U g U g M g M g ) using satellite DNAs obtained from flow-sorted chromosome 5M g . FISH was performed to localize the satellite DNAs...

...Manuel A. Garrido-Ramos For decades, satellite DNAs have been the hidden part of genomes. Initially considered as junk DNA, there is currently an increasing appreciation of the functional significance of satellite DNA repeats and of their sequences. Satellite DNA families accumulate...

... the DNA component is typically characterized by the presence of extended arrays of tandem repeats called satellite DNA. Here, we describe the isolation and characterization of a 137-bp-long new satellite DNA sequence from the horse genome (EC137), which is also present, even if less abundant...

...S.E. Vittorazzi; L.B. Lourenço; M.L. Del-Grande; S.M. Recco-Pimentel In the present study, we describe for the first time a family of 190-bp satellite DNA related to 5S rDNA in anurans and the existence of 2 forms of 5S rDNA, type I (201 bp) and type II (690 bp). The sequences were obtained from...
