Clustering genome data based on approximate matching

Patil, Nagamma; Toshniwal, Durga; Garg, Kumkum - In: International Journal of Data Analysis Techniques and … 5 (2013) 2, pp. 122-147

Genome data mining and knowledge extraction is an important problem in bioinformatics. Some research work has been done for genome identification based on exact matching of n-grams. However, in most real world biological problems, it may not be feasible to have an exact match, so approximate...

Global transposable characteristics in the complete DNA sequence of the yeast

Wu, Zuo-Bing - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 24, pp. 5698-5705

Global transposable characteristics in the complete DNA sequence of the Saccharomyces cevevisiae yeast is determined by using the metric representation and recurrence plot methods. On the basis of the correlation distance of nucleotide strings, 16 chromosome sequences of the yeast, which are...

From scale invariance to deterministic chaos in DNA sequences: towards a deterministic description of gene organization in the human genome

Nicolay, S.; Brodie of Brodie, E.B.; Touchon, M.; … - In: Physica A: Statistical Mechanics and its Applications 342 (2004) 1, pp. 270-280

We use the continuous wavelet transform to perform a space-scale analysis of the AT and GC skews (strand asymmetries) in human genomic sequences, which have been shown to correlate with gene transcription. This study reveals the existence of a characteristic scale ℓc≃25±10kb that separates...

Compositional spectrum—revealing patterns for genomic sequence characterization and comparison

Kirzhner, Valery M.; Korol, Abraham B.; Bolshoy, Alexander - In: Physica A: Statistical Mechanics and its Applications 312 (2002) 3, pp. 447-457

In this paper we propose a natural approach to characterizing genomic sequences, based on occurrences of fixed length words (strings over the alphabet {A,C,G,T}) from a sufficiently large set W of arbitrary (in general case) words. According to our approach, any genomic sequence can be...
