NCBI: A Digital Repository for Biological Sequences

The National Center for Biotechnology Information (NCBI) is a treasure trove of biological data, serving as a repository for DNA, RNA, and protein sequences from approximately 1,490 organisms, primarily post-Human Genome Project (HGP). This complex resource has been instrumental in advancing research, particularly in biology and genetics, and is accessible to researchers and scientists worldwide.

Origins and History of NCBI

The genesis of NCBI stems from the Human Genome Project, an ambitious and pioneering effort initiated with a budget of $3 billion. Legendary scientists like James Watson, Francis Crick, Francis Collins, Craig Venter, and Dr. Bernadine Healy, alongside prominent institutions such as the John Hopkins School, Sanger Institute, Department of Energy, NIH, NSF, CSHL, and Whitehead Institute, as well as Celera Genomics, collaborated to accomplish this mammoth task. The vision was to convert the massive data generated from sequencing into an actionable resource, leading to the creation of NCBI.

The Human Genome Project and NCBI

The Human Genome Project (HGP) was initiated to map the entire human genome, providing a foundation for advancing genetics, bioinformatics, and medical research. NCBI was born out of this initiative, and it has been instrumental in providing researchers with access to the vast amount of data generated during the HGP. The project's success was immensely recognized globally, and today, NCBI continues to evolve and expand, incorporating sequences from humans to pufferfish, published in the form of FASTA files.

Sequence Upload and Storage

Sequences from various species are meticulously uploaded and stored as FASTA files on NCBI. FASTA is a plain-text format for nucleotide sequences, which makes it amenable for rapid data exchange and analysis. NCBI utilizes C programming language for developing and mapping the sequences to XML, ensuring efficient and accurate data management.

A Specific Example: Serratia sp. MNR1 16S Ribosomal RNA Gene

To illustrate the kind of data stored on NCBI, consider the sequence of the Serratia sp. MNR1 16S ribosomal RNA gene, a partial sequence stored in GenBank accession number JX647841.1. This record can be accessed through a user-friendly interface that includes coding, graphics, and further analysis tools.
