New compilation of satellite DNA's

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1970
Abstract 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, 1971
Abstract 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

2021
The 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, 1971
Sheared 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, 1974
Abstract 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, 1986
We 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, 1973
Sheep 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 ...

Transcription of Satellite DNAs in Mammals

2010
Centromeric and pericentric regions have long been regarded as transcriptionally inert portions of chromosomes. A number of studies in the past 10 years disproved this dogma and provided convincing evidence that centromeric and pericentric sequences are transcriptionally active in several biological contexts.In this chapter, we provide a comprehensive ...

The diversity of satellite DNAs of Crustacea

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1972
Abstract 1. DNAs from six species of Crustacea were examined. Each contained one or two satellites, comprising up to 30 % of the total DNA. 2. Five ( A+T)-rich and three ( G+C)-rich satellites were isolated. Two of the former and two of the latter form multiple distinct bands in alkaline CsCl, indicating that the individual strands ...

On the tertiary structure of satellite DNA

Biochimie, 1992
The primary structure of the Citrus ichangensis satellite DNA repeating unit has been estimated. The repeat is 181 bp long and contains four pentanucleotides of adenine residues. Oligomer forms of the stDNA repeating unit were detected by a partial hydrolysis of the C ichangensis stDNA by BspI restriction endonuclease.
