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.,, Protein sequence databases are categorised as primary, composite or secondary. This is in order to determ, expressed together under different cellular conditions.
