The National Center for Biotechnology Information (NCBI) is a part of the U.S. National Library of Medicine, established in 1988. It provides access to a vast array of biological information, including databases for DNA sequences, protein structures, and scientific literature. NCBI's resources support research in fields like genetics, molecular biology, and bioinformatics. NCBI hosts several important databases, such as GenBank, which stores nucleotide sequences, and PubMed, a repository of biomedical literature. These tools are essential for researchers, healthcare professionals, and educators, facilitating the sharing and discovery of scientific knowledge in the life sciences.
