This method was used to identify members of the human hemoglobin gene family. The members this gene family descended from a single ancestral gene. 3. Genes were identified in a novel bacteriophage genome using bioinformatics programs that use algorithms to look for common features of open reading frames 4. Genomes of several species of bacteria were compared to identify common organization of genes 5. A sample of contaminated ground water was sequenced to identify the species diversity and relativ abundance of bacteria in the sample 6. A protein domain in a protein with unknown function was identified as an ion channel
