Bioinformatics and Genome Data Analysis Fredj Tekaia Institut Pasteur Introduction to the course

Access to entire genome sequences is revolutionizing our understanding of how genetic information is stored and organized in DNA, and how it has evolved over time. The sequence of a genome provides significant details of the gene catalogue within a species. Recent analysis and comparisons of complete genome sequences show the acceleration in the understanding of species organisation, links between genes, functions of the genes, evolution of genes of genomes and of species.

Complete genomes  >1387 projects  261 published ( ) 654 prokaryotes 472 eukaryotes

Number of available completely sequenced genomes

Huge amount of data with exponential increase

Few scientists are involved in generating data and much more are involved in data analysis

Genomics Is the study of genomes. (including the study of their genes, proteins, their sequences, functions, evolution,....)

Bioinformatics is needed to transform the flood of raw data (sequences) into scientific knowledge.

MathematicsStatistics Informatics Nucleotide & protein sequences and related informations Bioinformatics Biology

Bioinformatics: Is defined as the mathematical, statistical, computing methods and tools that, based on sequences and related informations, aims at solving biological questions.

Biological problem Pairwise sequence alignment Search for similar sequences Multiple sequence alignment Phylogenetic tree reconstruction Protein 3D structure alignment Math/Stat/Info Methods Dynamic programming (DP); Markov Chain, Monte Carlo, Gibbs samplers; Hidden Markov models (HMM); Motif extraction Functional site prediction Coding region prediction Transmembrane domain prediction Protein 3D structure prediction Discriminant analysis; Neural networks; Hidden Markov models (HMM); Formal grammar; Superfamily classification Ortholog/paralog clustering of genes Clustering algorithms Hierarchical, k-means,...; CA, PCA, MDS,...;
