1. Processing raw information: The experimentally determined sequence (raw information) is processed using bioinformatics tools into genes, the proteins encoded and their function, the regulatory sequences, and inferring phylogenetic relationships.
2. Genes: Gene prediction can be done by using computer programs like Gene Mark for bacterial genomes and GENSCAN for eukaryotes.
3. Proteins: Protein sequences can be inferred from the predicted genes by using simple computer programs.
4. Regulatory sequences: Regulatory sequences can also be identified and analysed by using bioinformatics tools.
5. Inferring phylogenetic relationships: Information regarding the relationships between organisms can be obtained by aligning multiple sequences, calculating evolutionary distance and constructing phylogenetic trees.
6. Making a Discovery: Using the bioinformatics tools and databases, the functions of unknown genes can be predicted.
