The mapping of genomes is not an end in itself. This data can be used to create new drugs, genetically altered foods and diagnostic kits. It is in the creation of new drugs that the science of genomics holds the maximum potential and bioinformatics provides the basic raw material for this. The science helps researchers in identifying new targets for drugs to act on. For instance, researchers trying to develop a better ACE inhibitor-can now search genome databases for sequences that resemble the enzyme and subsequently use that information to develop newer drugs.
