Tandem repeats finder: a program to analyze DNA sequences

Tandem repeats finder: a program to analyze DNA sequences.

A tandem repeat in DNA is two or more contiguous, approximate copies of a pattern of nucleotides. Tandem repeats have been shown to cause human disease, may play a variety of regulatory and evolutionary roles and are important laboratory and analytic tools. Extensive knowledge about pattern size, copy number, mutational history, etc. for tandem repeats has been limited by the inability to easil...

STRING: 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...

Filtering 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 ...

Expansion of tandem repeats and oligomer clustering in coding and noncoding DNA sequences

We review recent studies of distribution of dimeric tandem repeats and short oligomer clustering in DNA sequences. We nd that distribution of dimeric tandem repeats in coding DNA is exponential, while in noncoding DNA it often has long power-law tails. We explain this phenomenon using mutation models based on random multiplicative processes. We also develop a clustering measure based on percola...
