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.

The lower amount of 5 methylcytosine in DNA from bull sperm relative to DNA of other bovine tissues is a result of the absence of this minor base from several of the satellite DNAs in sperm. This applies particularly to the 1.715, 1.711b and 1.709 satellites and less so to the 1.706 and 1.711a satellites.

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,

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 ...

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 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.

Satellite DNA and cytogenetic evolution
Chromosoma, 1976The genus Dipodomys (kangaroo rats) exhibits major interspecies variations in the proportions of highly reiterated satellite DNA sequences in the genome as well as in the chromosome number and the proportions of uni-armed and bi-armed chromosomes.

Chromosomal Localization of Mouse Satellite DNA
Science, 1970Hybridization of radioactive nucleic acids with the DNA of cytological preparations shows that the sequences of mouse satellite DNA are located in the centromeric heterochromatin of the mouse chromosomes. Other types of heterochromatin in the cytological preparations do not contain satellite DNA.

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.
