Direct sequencing of the mitochondrial displacement loop (D-loop) of shrews (genus Sorex) for the region between the tRNA(Pro) and the conserved sequence block-F revealed variable numbers of 79-bp tandem repeats. These repeats were found in all 19 individuals sequenced, representing three subspecies and one closely related species of the masked shrew group (Sorex cinereus cinereus, S. c. miscix...

A 'tandem repeat' in DNA is a sequence of two or more contiguous, approximate copies of a pattern of nucleotides. Tandem repeats are common in the genomes of both eukaryotic and prokaryotic organisms. They are significant markers for human identity testing, disease diagnosis, sequence homology and population studies. In this article, we describe a new database, TRedD, which contains the tandem ...

MOTIVATION Tandem repeats are associated with disease genes, play an important role in evolution and are important in genomic organization and function. Although much research has been done on short perfect patterns of repeats, there has been less focus on imperfect repeats. Thus, there is an acute need for a tandem repeats database that provides reliable and up to date information on both perf...

A tandem repeat (or square) is a string aa; where a is a non-empty string. We present an OðjSjÞ-time algorithm that operates on the suffix tree TðSÞ for a string S; finding and marking the endpoint in TðSÞ of every tandem repeat that occurs in S: This decorated suffix tree implicitly represents all occurrences of tandem repeats in S; and can be used to efficiently solve many questions concernin...

MOTIVATION A tandem repeat in DNA is a sequence of two or more contiguous, approximate copies of a pattern of nucleotides. Tandem repeats occur in the genomes of both eukaryotic and prokaryotic organisms. They are important in numerous fields including disease diagnosis, mapping studies, human identity testing (DNA fingerprinting), sequence homology and population studies. Although tandem repea...

Approximate tandem repeats in a genomic sequence are two or more contiguous, similar copies of a pattern of nucleotides. They are used in DNA mapping, studying molecular evolution mechanisms, forensic analysis and research in diagnosis of inherited diseases. All their functions are still investigated and not well defined, but increasing biological databases together with tools for identificatio...

BACKGROUND Ancestral reconstructions of mammalian genomes have revealed that evolutionary breakpoint regions are clustered in regions that are more prone to break and reorganize. What is still unclear to evolutionary biologists is whether these regions are physically unstable due solely to sequence composition and/or genome organization, or do they represent genomic areas where the selection ag...
