National Center for Biotechnology Information (NCBI)
The National Center for Biotechnology Information (NCBI) is a part of the National Library of Medicine, at the National Institutes of Health. Its mission is to organize DNA sequence and related data in such a way that it is available for investigators to use and analyze. This has involved the provision of tools such as BLAST, the sequence similarity search tool, and the design of search engines, such as PubMed, for mining the biomedical abstracts database, MEDLINE.
