ABSTRACT
Many Computational methods are yet available for data retrieval and analysis of genomic sequences, but some functional sites are difficult to characterize. In this work, we examine the problem of promoter localization in human DNA sequences. Promoters are regulatory regions that governs the expression of genes, and their prediction is reputed difficult, so that this issue is still open. We present the Chaos Game representation (CGR) of DNA sequences which has many interesting properties, and the notion of ‘genomic signature’ that proved relevant in phylogeny applications. Based on this notion, we develop a (naïve) bayesian classifier, evaluate its performances, and show that its adaptive implementation enable to reveal or assess core-promoter positions along a DNA sequence. © 2006 American Institute of Physics

    Summary. The complete nucleotide sequence of columbid circovirus (CoCV) isolated from pigeons is described. CoCV was amplified using a consensus primer PCR approach directed against conserved sequences within the rep genes of vertebrate circoviruses. The genome of CoCV is circular and 2037 nt in...

    Species trees are an essential tool in conservation and evolutionary biology. In phylogenomics, not only is data choice (e.g. using unlinked orthologs rather than paralogs) an important systematic consideration, but the choice of phylogenetic algorithm is also important. Since individual gene...
