An efficient and accurate distance based algorithm to reconstruct tandem duplication trees
UNLABELLED The problem of reconstructing the duplication tree of a set of tandemly repeated sequences which are supposed to have arisen through unequal recombination, was first introduced by Fitch (1977, Genetics, 86, 93-104), and has recently received a lot of attention. In this paper, we describe DTSCORE, a fast distance based algorithm to reconstruct tandem duplication trees, which is statis...
متن کاملAn Exact and Polynomial Distance-Based Algorithm to Reconstruct Single Copy Tandem Duplication Trees
The problem of reconstructing the duplication tree of a set of tandemly repeated sequences which are supposed to have arisen by unequal recombination, was first introduced by Fitch (1977), and has recently received a lot of attention. In this paper, we place ourselves in a distance framework and deal with the restricted problem of reconstructing single copy duplication trees. We describe an exa...
متن کاملThe combinatorics of tandem duplication trees.
We developed a recurrence relation that counts the number of tandem duplication trees (either rooted or unrooted) that are consistent with a set of n tandemly repeated sequences generated under the standard unequal recombination (or crossover) model of tandem duplications. The number of rooted duplication trees is exactly twice the number of unrooted trees, which means that on average only two ...
متن کاملLETTER On Counting Tandem Duplication Trees
Large genomes are full of repeated DNA sequences. It was estimated that over half of the human DNA consists of repeated sequences (Baltimore 2001; Eichler 2001; Leem et al. 2002). Tandem duplication is one of the important evolutionary mechanisms for producing repeated DNA sequences, in which the copies that may or may not contain genes are adjacent along the genome. Fitch (1977) first observed...
متن کاملAn accurate and efficient algorithm for Peptide and ptm identification by tandem mass spectrometry.
Peptide identification by tandem mass spectrometry (MS/MS) is one of the most important problems in proteomics. Recent advances in high throughput MS/MS experiments result in huge amount of spectra. Unfortunately, identification of these spectra is relatively slow, and the accuracies of current algorithms are not high with the presence of noises and post-translational modifications (PTMs). In t...
