Conservation of highly repetitive DNA in cetaceans

Chromosoma, 1984
It is controversial whether odontocetes (toothed whales) and mysticetes (whalebone whales) have a common ancestry. Cetacean karyological uniformity, which is unique among mammalian orders, suggests a monophyletic origin; however, several anatomical authorities have maintained that odontocetes and mysticetes are diphyletic.

Moderately Repetitive DNA in Evolution

1982
Publisher Summary This chapter discusses the role of moderately repetitive DNA in evolution. Moderately repetitive sequences are found as dispersed segments among unrelated, often single-copy DNA sequences throughout the genome, while simple-sequence DNAs occur in long tandemly repeated clusters, frequently at the centromeric or telomeric regions of ...

Repetition structure of mammalian nuclear DNA

Journal of Theoretical Biology, 1990
We 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, 2019
We 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, 1993
We 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.

Terminal repetition in the DNA of bacteriophage T5

Journal of Molecular Biology, 1972
Abstract The DNA of bacteriophage T5 can be shown to be terminally repetitious by annealing after partial digestion with λ exonuclease. Under these conditions circular molecules are formed both before and after repair of the natural singlechain interruptions with polynucleotide ligase.

Diagnostic applications of repetitive DNA sequences

Clinica Chimica Acta, 1992
Different diagnostic applications are discussed for various categories of repetitive DNA sequences. Since all eukaryotes are characterized by genomic redundancy, these sensitive, rapid, and comparatively simple techniques are revolutionizing many fields in clinical and experimental diagnostics.

Cloning and expansion of repetitive DNA sequences

Repeat and structure-prone DNA sequences comprise a large proportion of the human genome. The instability of these sequences has been implicated in a range of diseases, including cancers and neurodegenerative disorders. However, the mechanism of pathogenicity is poorly understood. As such, further studies on repetitive DNA are required.
