Roughly, bioinformatics describes any use of computers to handle biological information. Identification of transcription factors in genomes, invariably depends on similarity search strategies, which assume a functi, evolutionary relationship between homologous proteins. At a structural level, we, predict there to be a finite number of different tertiary structures, There are common terms to describe the relationship between pairs of proteins or the, genes from which they are derived: analogous proteins have related folds, but unrelated, two categories can sometimes be difficult to distinguish especially if the relationship, distinguish between orthologues, proteins in different species that have evolved from a, common ancestral gene, and paralogues, proteins that are related by gene duplication, An important concept that arises from these observations is that of a finite “parts list” for. Briefly, the most common methods, methods originally derived from algorithms to constru, clustered first, and those with more diverse profiles are included iteratively, clusters are initially assigned randomly, and the genes are regrouped iterati, Given these methods, it is of interest to relate the expression data to other attributes such, as structure, function and subcellular localisation of each gene product.

Here we take a broad view and include, that may not normally be listed. Lastly, we discuss the promises of gene microarrays and proteomics, developing technologies that allow the parallel analyses of tissue expression patterns of thousands of genes or proteins, respectively. The third aim is to use these tools to analyse the data . Taking protein folds as an example, we mentioned that with a few exceptions, the tertiary, structures of proteins adopt one of a limited rep. different fold families is considerably smaller than the number of gene families, categorising the proteins by fold provides a substantial simplification of the contents of a, genome. For raw DNA sequences, investigations involve separating coding and non, introns, exons and promoter regions for annotating genomic DNA, sequences, analyses include developing algorithms for sequence comparisons, domains from conserved sequence motifs in such alignments. Structural genomics, demonstrating similarity to proteins of known structure, that prokaryotic transcription factors most frequently contain helix, leucine zipper motifs. Since molecular biology data are distributed among to build phylogenetic trees that trace the evolution of whole organisms. www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=Protein, www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=Genome, Protein sequence databases are categorised as primary, composite or secondary.
