DOI: 10.1038/s41467-024-49567-5
Abstract: RNA Polymerase (RNAP) II transcription on non-coding repetitive satellite DNAs plays an important role in chromosome segregation, but a little is known about the regulation of satellite transcription. We here show that Topoisomerase I (TopI),… read more here.

DOI: 10.3390/genes14020418
Abstract: Among Meliponini species, c-heterochromatin can occupy large portions of chromosomes. This characteristic could be useful for understanding evolutionary patterns of satellite DNAs (satDNAs), although few sequences have been characterized in these bees. In Trigona, phylogenetically… read more here.

DOI: 10.3390/genes14030742
Abstract: According to the established classical view, satellite DNAs are defined as abundant non-coding DNA sequences repeated in tandem that build long arrays located in heterochromatin. Advances in sequencing methodologies and development of specialized bioinformatics tools… read more here.

DOI: 10.36253/caryologia-1939
Abstract: Satellite DNAs such as Cap-A sequences are potentially informative taxonomic and phylogenetic markers useful for characterizing primate genomes. They have also been used as cytogenetic markers facilitating species identification in many taxa. The aim of… read more here.
