UNRAVEL THE COMPLEX STRANDS OF BIOLOGICAL SEQUENCES
GenBank ® is the NIH genetic sequence database, an annotated collection of all publicly available DNA sequences. GenBank is part of the International Nucleotide Sequence Database Collaboration, which comprises the DNA DataBank of Japan (DDBJ), the European Nucleotide Archive (ENA), and GenBank at NCBI. These three organizations exchange data on a daily basis.
From its inception in 1982, GenBank is constantly growing at an exponential rate, doubling every 18 months. With over 228 billion nucleotide bases from more than 199 million (on Feb 2017) individual sequences GenBank provides access within the scientific community to the most up-to-date and wide-ranging DNA sequence information.
