The function and regulation of repetitive DNA, the 'dark matter' of the genome, is still only rudimentarily understood. Now a study investigating DNA replication of repetitive centromeric chromosome segments has started to expose a fascinating replication program that involves suppression of ATR signalling, in particular during replication stress.

BETWEEN 10% and 70% of the nuclear DNA of all higher organisms consists of repeating sequences1,2 (in some organisms only 6–13 base pairs long3) which comprise families of identical or similar base sequences repeated from several hundred to more than a million times.

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 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 ...

Transcription of repetitive DNA in Neurospora crassa
Molecular and General Genetics MGG, 1975Repeated DNA sequences of Neurospora crassa were isolated and characterized. Approximately 10-12% of N. crassa DNA sequence were repeated, of which 7.3% were found to be transcribed in mid-log phase of mycelial growth as measured by DNA:RNA hybridization. It is suggested that part of repetitive DNA transcripts in N.

It is well established that conifer genomes are comprised largely of noncoding and repetitive DNA (Chaps. 2 and 3). However, the much smaller fraction of the genome comprised of protein-coding genes has been the focus of most research (see Chaps. 5, 6, and 7) because these genes ultimately lead to phenotypes and the genetic differences among species ...

Characterization of Repetitive DNA Elements in Arabidopsis
Journal of Molecular Evolution, 1999We have applied computational methods to the available database and identified several families of repetitive DNA elements in the Arabidopsis thaliana genome. While some of the elements have features expected of either miniature inverted-repeat transposable elements (MITEs) or retrotransposons, the most abundant class of repetitive elements, the AthE1 ...

Repetitive shuttling of a motor protein on DNA
Nature, 2005Many helicases modulate recombination, an essential process that needs to be tightly controlled. Mutations in some human disease helicases cause increased recombination, genome instability and cancer. To elucidate the potential mode of action of these enzymes, here we developed a single-molecule fluorescence assay that can visualize DNA binding and ...
