GenBank Database

GenBank is the NIH genetic sequence database, an annotated collection of all publicly available DNA sequences. GenBank (at NCBI), together with the DNA DataBank of Japan (DDBJ) and the European Molecular Biology Laboratory (EMBL) comprise the International Nucleotide Sequence Database Collaboration. These three organizations exchange data on a daily basis. GenBank grows at an exponential rate, with the number of nucleotide bases doubling approximately every 14 months. Currently, GenBank contains more than 13 billion bases from over 100,000 species.
