GenBank，NIH 的遗传序列数据库，收集了所有已公开发表的DNA序列

GenBank^® is the NIH genetic sequence database, an annotated collection of all publicly available DNA sequences (Nucleic Acids Research 2004 Jan 1;32(1):23-6). There are approximately 37,893,844,733 bases in 32,549,400 sequence records as of February 2004 (see GenBank growth statistics). GenBank records are annotated using a standard set of biological terms and show these annotations in a Feature Table. As an example, you may view the record for a Saccharomyces cerevisiae gene. The complete release notes for the current version of GenBank are available. A new release is made every two months. GenBank is part of the International Nucleotide Sequence Database Collaboration, which comprises the DNA DataBank of Japan (DDBJ), the European Molecular Biology Laboratory (EMBL), and GenBank at NCBI. These three organizations exchange data on a daily basis.
