The GenBank sequence database is an open access, annotated collection of all publicly available nucleotide sequences and their protein translations.
This database is produced at National Center for Biotechnology Information (NCBI) as part of the International Nucleotide Sequence Database Collaboration, or INSDC.
GenBank and its collaborators receive sequences produced in laboratories throughout the world from more than 100,000 distinct organisms.
GenBank continues to grow at an exponential rate, doubling every 10 months.
Release 155, produced in August 2006, contained over 65 billion nucleotide bases in more than 61 million sequences.
GenBank is built by direct submissions from individual laboratories, as well as from bulk submissions from large-scale sequencing centers.
