Interspersed repetitive DNA sequences are unlikely to be parasitic
Journal of Theoretical Biology, 1982Abstract Short interspersed repetitive sequences have been found in the DNA of all eukaryotes studied. This paper examines, using computer simulation, the possibility that such sequences are parasitic and that their interspersion is a means of maximizing recombination between gene copies and with it the ability of such genes to invade a population by

A new family of interspersed repetitive DNA sequences in the mouse genome
Journal of Molecular Biology, 1982Abstract Repetitive DNA sequences near immunoglobulin genes in the mouse genome (Steinmetz et al., 1980a,b) were characterized by restriction mapping and hybridization. Six sequences were determined that turned out to belong to a new family of dispersed repetitive DNA.

Interspersion of repetitive and nonrepetitive DNA sequences in the Drosophila melanogaster genome
Cell, 1975Cot analysis shows that the haploid Drosophila genome contains 12 percent rapidly reassociating, highly reiterated DNA, 12 percent middle repetitive DNA with an average reiteration frequency of 70, and 70 percent single-copy DNA. The distribution of the middle repetitive sequences in the genome has been studied by an examination in the electron ...

Absence of short-period repetitive-sequence interspersion in the Basidiomycete Schizophyllum commune
Chromosoma, 1980Reassociation kinetics and electron microscopy were used to examine the organization of DNA sequences in the Basidiomycete Schizophyllum commune. Short-period interspersion of repetitive and unique sequences is absent from the DNA of this wood-rotting fungus.

Dispersal process associated with the L1 family of interspersed repetitive DNA sequences
Journal of Molecular Biology, 1984We have determined the complete nucleotide sequence for five members of the L1Md repetitive family from the beta-globin gene region of the BALB/c mouse. The five repeats are different lengths, each terminating at the 5' end at different points with respect to one another.

Interspersion of Short Repetitive Sequences Studied in Cloned Sea Urchin DNA Fragments
Science, 1977The length and spacing of repetitive sequence elements were studied in several cloned sea urchin DNA fragments. Sequence organization in these fragments was found to be of the short interspersed form expected for sea urchin DNA, and for one clone the evidence shows that nearby repeats do not belong to the same repetitive sequence family.

Message sequences and short repetitive sequences are interspersed in sea urchin egg poly(A)+ RNAs
Nature, 1980At least half of the mass and most of the different single-copy maternal mRNA sequences in the egg are covalently associated with transcripts of short repetitive sequences. Only a restricted group of the diverse genomic repeat families are significantly represented.

Chromosoma, 1976
A sensitive search has been made in Drosophila melanogaster DNA for short repetitive sequences interspersed with single copy sequences. Five kinds of measurements all yield the conclusion that there are few short repetitive sequences in this genome: () Comparison of the kinetics of reassociation of short (360 nucleotide) and long (1,830 nucleotide ...

The structure of three members of a repetitive DNA family from the genome of the nematode Caenorhabditis elegans has been studied. The three repetitive elements have a similar unitary structure consisting of two 451-bp sequences in inverted orientation separated by 491 bp, 1.5 kb, and 2.5 kb, respectively.

In these studies we show that the moderately repetitive DNA sequences of Caenorhabditis elegans are not arranged in the characteristic short-period interspersion pattern of most eukaryotes. Rather, the moderately repetitive sequences are arranged in long arrays as in Drosophila and Apis.
