Satellite DNAs represent the most abundant fraction of repetitive sequences in genomes of almost all eukaryotic species. Long arrays of satellite DNA monomers form densely packed heterochromatic genome compartments and also span over the functionally important centromere locus.

Nuclear satellite DNAs of yeast
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1972High molecular weight DNA isolated from yeast nuclei has been fractionated in Ag+-Cs2SO4 and Hg2+-Cs2SO4 density gradients. Centrifugation in Ag+-Cs2SO4 gradients resulted in the appearance of a satellite band on the heavy side of the gradients. This satellite DNA, which accounts for 3–5 % of the total DNA, does not code for either 26-S, 17-S and 5 ...

Nature, 1971
The mystery of how satellite DNA came to be so widespread in plants and animals could be solved if this DNA conferred an advantage on the chromosome which carried it. This advantage might be an improved ability to stand up to the rigours of meiosis.

New compilation of satellite DNA's
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1970Abstract Equilibrium CsCl density gradient ultracentrifugation is one of the most useful methods for DNA analysis. The abundance of satellite DNA's thus described during the last few years may be somewhat disconcerting. Even after discarding the cases of chloroplastic and mitochondrial DNA's (of such origin or assumed to be so), the amount of reports,

Satellite DNA in calf heterochromatin
Experimental Cell Research, 1971Abstract Analysis of nuclear DNA from calf liver by Cs 2 SO 4 -Ag + density gradient centrifugation revealed a minor heavy peak (7% of the total DNA) at a density of 1.57 g/cm 3 , a main peak at a density of 1.51 g/cm 3 and a minor light peak (3% of the total DNA) at a density of 1.44 g/cm 3 . Upon fractionation of total chromatin into constitutive

The Genomics of Plant Satellite DNA
2021The twenty-first century began with a certain indifference to the research of satellite DNA (satDNA). Neither genome sequencing projects were able to accurately encompass the study of satDNA nor classic methodologies were able to go further in undertaking a better comprehensive study of the whole set of satDNA sequences of a genome.

The cyclization of mouse satellite DNA
Chromosoma, 1971Sheared fragments of mouse satellite DNA can form rings and other circular structures by several techniques. „Folded rings“ are formed if the sheared fragments are simply annealed, indicating that shearing produces single-chain terminals, and that the repetitious sequence is shorter than the exposed ends.

Complexity of human satellite A DNA
Biochemical and Biophysical Research Communications, 1974Abstract Satellite A DNA of human origin having a molecular weight of eight million daltons has been isolated. This DNA species has a 51% G+C content and is composed of two kinetically distinct reassociating components. On the average the fast component is repeated 1600 times more frequently than the slow component.

Satellite DNA in the crustacean Artemia
Gene, 1986We have isolated a satellite fraction from the Artemia genome by both restriction endonuclease digestion and equilibrium density centrifugation in CsCl gradients containing ligand dye Hoechst 33258. Satellite DNA was arranged in long stretches (approx. 23 kb) of tandem repeats of a basic unit of 113 bp.

Satellite DNA in the sheep and goat
Biochemical Genetics, 1973Sheep and goats possess closely similar satellite DNAs which seem to be concentrated in the heterochromatin and the nucleolus. In both species, the major and minor satellites have buoyant densities of 1.711 g·cm −3 and 1.718 g·cm −3 and represent 12% and 2.5%, respectively, of the ...
