Tandemly repeated sequences in the mitochondrial DNA control region and phylogeography of the Pike-Perches Stizostedion.
DNA sequences from the mitochondrial DNA control region are used to test the phylogeographic relationships among the pike-perches, Stizostedion (Teleostei: Percidae) and to examine patterns of variation. Sequences reveal two types of variability: single nucleotide polymorphisms and 6 to 14 copies of 10- to 11-base-pair tandemly repeated sequences. Numbers of copies of the tandem repeats are fou...
متن کاملMolecular characterization of a family of tandemly repeated DNA sequences, TR-1, in heterochromatic knobs of maize and its relatives.
Two families of tandem repeats, 180-bp and TR-1, have been found in the knobs of maize. In this study, we isolated 59 clones belonging to the TR-1 family from maize and teosinte. Southern hybridization and sequence analysis revealed that members of this family are composed of three basic sequences, A (67 bp); B (184 bp) or its variants B' (184 bp), 2/3B (115 bp), 2/3B' (115 bp); and C (108 bp),...
متن کاملEvolution of Tandemly Repeated Sequences Through Duplication and Inversion
Given a phylogenetic tree T for a family of tandemly repeated genes and their signed order O on the chromosome, we aim to find the minimum number of inversions compatible with an evolutionary history of this family. This is the first attempt to account for inversions in an evolutionary model of tandemly repeated genes. We present a time-efficient branch-and-bound algorithm and show, using simul...
متن کاملTRAP: automated classification, quantification and annotation of tandemly repeated sequences
TRAP, the Tandem Repeats Analysis Program, is a Perl program that provides a unified set of analyses for the selection, classification, quantification and automated annotation of tandemly repeated sequences. TRAP uses the results of the Tandem Repeats Finder program to perform a global analysis of the satellite content of DNA sequences, permitting researchers to easily assess the tandem repeat ...
متن کاملRepeated DNA sequences in fungi.
Several fungal species, representatives of all broad groups like basidiomycetes, ascomycetes and phycomycetes, were examined for the nature of repeated DNA sequences by DNA:DNA reassociation studies using hydroxyapatite chromatography. All of the fungal species tested contained 10-20% repeated DNA sequences. There are approximately 100-110 copies of repeated DNA sequences of approximately 4 x 1...
