Repetitive sequences in the crocodilian mitochondrial control region: poly-A sequences and heteroplasmic tandem repeats.
Heteroplasmic tandem repeats in the mitochondrial control region have been documented in a wide variety of vertebrate species. We have examined the control region from 11 species in the family Crocodylidae and identified two different types of heteroplasmic repetitive sequences in the conserved sequence block (CSB) domain-an extensive poly-A tract that appears to be involved in the formation of...
متن کاملShort tandem repeats and genetic variation.
Single nucleotide polymorphisms (SNPs) are widely distributed in the human genome and although most SNPs are the result of independent point-mutations, there are exceptions. When studying distances between SNPs, a periodic pattern in the distance between pairs of identical SNPs has been found to be heavily correlated with periodicity in short tandem repeats (STRs). STRs are short DNA segments, ...
متن کاملAn efficient algorithm for finding short approximate non-tandem repeats
We study the problem of approximate non-tandem repeat extraction. Given a long subject string S of length N over a finite alphabet Sigma and a threshold D, we would like to find all short substrings of S of length P that repeat with at most D differences, i.e., insertions, deletions, and mismatches. We give a careful theoretical characterization of the set of seeds (i.e., some maximal exact rep...
متن کاملFiltering Tandem Repeats in DNA Sequences
A tandem repeat is a sequence of two or more contiguous, approximate copies of a pattern. 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 repeats have been used by biologists ...
متن کاملSTRING: finding tandem repeats in DNA sequences
MOTIVATION AND RESULTS The importance of Tandem Repeats in some genomes is now well established. We have reported elsewhere some interesting new results obtained by means of a preliminary program for finding Tandem Repeats in DNA sequences, together with a brief description of the basic ideas of the algorithm. We describe here a completely new program based only in part on those ideas, we brief...
