What is 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.
