Circular, repetitive DNA in yeast
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1972Abstract The fraction of repetitive DNA and the small circular DNA with nuclear density from Saccharomyces cerevisiae are shown to be identical.

Repetitive DNA of microtus agrestis
Biochemical and Biophysical Research Communications, 1971Abstract DNA from the European field vole Microtus agrestis was sheared to fragments approximately 500 nucleotides in length in a French pressure cell and fractionated according to repetitiveness on hydroxyapatite. Four fractions, amounting to 26% of the total DNA, were obtained at Cot values between 2×10−4 and 8×10−1. Analysis of the fractions

Repetitive DNA in eukaryotic genomes
Chromosome Research, 2015Repetitive DNA--sequence motifs repeated hundreds or thousands of times in the genome--makes up the major proportion of all the nuclear DNA in most eukaryotic genomes. However, the significance of repetitive DNA in the genome is not completely understood, and it has been considered to have both structural and functional roles, or perhaps even no ...

Evolution ofDrosophila repetitive-dispersed DNA
Journal of Molecular Evolution, 1983We have examined the phylogenetic distribution of a spectrum of Drosophila repetitive-dispersed DNAs ranging from structurally complex transposable elements to scrambled middle repetitive sequences. Our data suggest that unlike typical "genes" these DNAs are unstable components of the drosophilid genome.

Repetitive DNA: genomic dark matter matters
Nature Reviews Genetics, 2021Neil Gemmell recalls the pioneering work published in 1968 by Britten and Kohne, which ignited in him an enduring fascination as to why eukaryotic genomes contain substantial fractions of repetitive DNA.

Repetition structure of mammalian nuclear DNA
Journal of Theoretical Biology, 1990We have used Fragmentation Sequencing logic to analyse the repetition structure of several large human genomic genes. The method, based on a proposed laboratory scheme for DNA sequencing, detects short sequences which are repeated near, but not necessarily adjacent, to each other (cryptically simple DNA). We find a low frequency of such repeats.

Addressable DNA nanotubes with repetitive components
Nanoscale, 2019We present a new strategy to produce DNA nanotubes based on canonical SSTs with addressability available along the axial direction of the self-assembled tubes, which are also programmably repetitive along the lateral direction.

Characterization of Murine Middle Repetitive DNA
DNA and Cell Biology, 1993We have characterized four sequences from a small library containing a subset of the repetitive families of the mouse. Each clone has a repetition frequency of less than 1,100 copies per genome and each clone represents a unique family of middle repetitive DNA.

Repetitive DNA and polyploidy in selachians
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19821. The DNA reassociation kinetics have been studied in 6 selachian species: Raja asterias, Raja montagui, Dasyatis violacea, Torpedo marmorata, Torpedo ocellata and Oxynotus centrina. 2. The results obtained show that the genomes of the two Torpedo, Dasyatis and Oxynotus are polyploid if compared with those of the two rays, though this finds no ...
