a sequence profiling tool in bioinformatics is a type of software that presents information related to a genetic sequence, gene name, or keyword input. such tools generally take a query such as a dna, rna, or protein sequence or ‘keyword’ and search one or more databases for information related to that sequence. summaries and aggregate results are provided in standardized format describing the information that would otherwise have required visits to many smaller sites or direct literature searches to compile. many sequence profiling tools are software portals or gateways that simplify the process of finding information about a query in the large and growing number of bioinformatics databases. the access to these kinds of tools is either web based or locally downloadable executables.
