Enter a few words about your sequence data.
GenBank is the world's largest nucleotide archive containing sequences from all branches of life and building a foundation for medical and biological discovery.
Sequence Read Archive (SRA)
SRA is the largest, publicly available repository of high throughput sequencing data. The archive accepts data from all branches of life as well as metagenomic and environmental surveys.
Sequence Submission FAQ
An accession number in bioinformatics is a unique identifier given to a DNA or protein sequence record to allow for tracking of different versions of that sequence record and the associated sequence over time in a single data repository. Because of its relative stability, accession numbers can be utilized as foreign keys for referring to a sequence object, but not necessarily to a unique sequence. All sequence information repositories implement the concept of "accession number" but might do so with subtle variation.
