Finding approximate tandem repeats in genomic sequences [PDF]

Proceedings of the eighth annual international conference on Computational molecular biology - RECOMB '04, 2004
An efficient algorithm is presented for detecting approximate tandem repeats in genomic sequences. The algorithm is based on a flexible statistical model which allows a wide range of definitions of approximate tandem repeats. The ideas and methods underlying the algorithm are described and its effectiveness on genomic data is demonstrated.

IMPACT OF TANDEM REPEATS ON THE SCALING OF NUCLEOTIDE SEQUENCES [PDF]

International Journal of Bifurcation and Chaos, 2006
Techniques such as detrended fluctuation analysis (DFA) and its extensions have been widely used to determine the nature of scaling in nucleotide sequences. In this brief communication we show that tandem repeats which are ubiquitous in nucleotide sequences can prevent reliable estimation of possible long-range correlations. Therefore, it is important

Locating tandem repeats in weighted sequences in proteins [PDF]

BMC Bioinformatics, 2013
Abstract A weighted biological sequence is a string in which a set of characters may appear at each position with respective probabilities of occurrence. We attempt to locate all the tandem repeats in a weighted sequence. A repeated substring is called a tandem repeat if each occurrence of the substring is directly adjacent to each other.

Short Tandem Repeat-Enriched Architectural RNAs in Nuclear Bodies: Functions and Associated Diseases

Non-Coding RNA, 2020
Nuclear bodies are membraneless, phase-separated compartments that concentrate specific proteins and RNAs in the nucleus. They are believed to serve as sites for the modification, sequestration, and storage of specific factors, and to act as ...

The Singular Evolution of Olea Genome Structure

Frontiers in Plant Science, 2022
The current view of plant genome evolution proposes that genome size has mainly been determined by polyploidisation and amplification/loss of transposons, with a minor role played by other repeated sequences, such as tandem repeats.

Immune activation by a multigene family of lectins with variable tandem repeats in oriental river prawn (Macrobrachium nipponense) [PDF]

Open Biology, 2020
Genomic regions with repeated sequences are unstable and prone to rapid DNA diversification. However, the role of tandem repeats within the coding region is not fully characterized.

STRING: finding tandem repeats in DNA sequences [PDF]

Bioinformatics, 2003
Abstract 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.

Structural characteristics of a mitochondrial control region from Myotis bat (Vespertilionidae) mitogenomes based on sequence datasets

Data in Brief, 2019
The datasets included sequences of a control region from Myotis bat mitogenomes. The control region (1706–2005 bp) of the Myotis mitogenomes was divided into three domains similar to that of other mammals, which included the common conserved blocks (ETAS

Genome-wide survey of tandem repeats by nanopore sequencing shows that disease-associated repeats are more polymorphic in the general population

BMC Medical Genomics, 2021
Background Tandem repeats are highly mutable and contribute to the development of human disease by a variety of mechanisms. It is difficult to predict which tandem repeats may cause a disease.
