The database is produced in an international collaboration with GenBank (USA) and the DNA Database of Japan (DDBJ). Each of the three groups collects a portion of the total sequence data reported worldwide, and all new and updated database entries are exchanged between the groups on a daily basis.

Established in 1988 as a national resource for molecular biology information, NCBI creates public databases, conducts research in computational biology, develops software tools for analyzing genome data, and disseminates biomedical information - all for the better understanding of molecular processes affecting human health and disease.

Areas of Interest:

• Create public databases
• Conduct research in computational biology
• Development of software for genome data analysis

It mainly contains:

• GenBank
• Literature Databases
• Molecular Databases
• Genomic Biology
• Tool (Data Mining)
