Statistics and Data
Basic Local Alignment Search Tool (BLAST) finds regions of local similarity between biological sequences; the program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance of matches. BLAST can be used to infer functional and evolutionary relationships between sequences as well as help identify members of gene families.
Public-domain archive of simple genetic polymorphisms in a variety of model eukaryotes, including single-base nucleotide substitutions (SNPs) as well as small-scale multi-base deletions or insertions, and retroposable element insertions and microsatellite repeat variations. Each dbSNP entry includes the sequence context of the polymorphism (i.e., the surrounding sequence), the occurrence frequency of the polymorphism (by population or individual), and the experimental method(s), protocols, and conditions used to assay the variation.
Provides data sets resulting from an automated genome analysis and annotation process for selected eukaryotic (primarily vertebrate) genomes. The Ensemble software system aims to provide accurate, automatic analysis of genome data; analysis and annotation maintained on the current data; presentation of the analysis to all via the web; and means of distribution of the analysis to users. Data can be accessed through text search and genome/chromosome browser functions. Through a data upload and distributed annotation system, Ensembl offers users the ability to display their own data sets in the genome browser framework; users may also share data with others.
Overviews and allows text-based searches of over 25 of the bibliographic databases and biomolecular data resources held at NCBI (the National Center for Biotechnology Information), including PubMed, OMIM, Entrez Gene, and Entrez Taxonomy; this site performs a simultaneous search of the various databases and reports back the number of hits in each -- you can then select an individual database to view detailed search results.
Searchable database of genes from a wide range of organisms, supplying key connections to other databases providing map, sequence, expression, structure, function, citation, and homology data; a good starting point for investigating the structure and role of a particular gene.

The number of bases in these databases continues to grow at an exponential rate. As of April 2006, there are over 130 billion bases in GenBank and RefSeq alone.
Provides text-based searching of records in the Molecular Modeling Database (MMDB), containing 3D macromolecular structures of proteins and polynucleotides; links to the Cn3D structure viewer program (download required). MMDB contains over 28,000 structures and is linked to other NCBI databases including sequences, bibliographic citations, taxonomic classifications, and sequence and structure neighbors.

Suite of databases and associated software, integrating current knowledge on the function and utility of biological systems (PATHWAY and BRITE databases), information about genes and proteins (GENES database), and chemical compounds and reactions (LIGAND database). KEGG is especially noted for its metabolic pathway database.
The major 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. Includes bibliographic and data resources such as PubMed, GenBank, OMIM, and many more.
The Map Viewer provides special browsing capabilities for a subset of organisms in Entrez Genomes. Map Viewer allows you to view and search an organism's complete genome, display chromosome maps, and zoom into progressively greater levels of detail, down to the sequence data for a region of interest. The number and types of available maps vary by organism, and are described in the "data and search tips" file for each organism. If multiple maps are available for a chromosome, it displays them aligned to each other based on shared marker and gene names, and, for the sequence maps, based on a common sequence coordinate system.
PDB is the single worldwide repository for the processing and distribution of 3-D structure data of large molecules of proteins and nucleic acids; the site provides a variety of tools and resources for studying the structures of biological macromolecules and their relationships to sequence, function, and disease.
PubChem provides information on the biological activities of small molecules. It is organized as three linked databases within the NCBI's Entrez information retrieval system. These are PubChem Substance, PubChem Compound, and PubChem BioAssay. PubChem also provides a fast chemical structure similarity search tool. Links from PubChem's chemical structure records to other Entrez databases provide information on biological properties.
The Genome Browser provides a visual display of chromosomal informaiton, allowing zoom and scroll over chromosomal and DNA sequence, showing the work of annotators worldwide. Other tools included on the site provide other means of accessing genomic and proteomic data: Gene Sorter shows expression, homology and other information on groups of genes that can be related in many ways; Blat quickly maps your sequence to the genome; Table Browser provides convenient access to the underlying database; VisiGene lets you browse through a large collection of in situ mouse and frog images to examine expression patterns. The site contains the reference sequence and working draft assemblies for a large collection of genomes. It also provides a portal to the ENCODE genome annotation project.
