Entrez Genome database is a collection of complete large-scale sequencing,
assembly, annotation, and mapping projects for cellular organisms.
Genome Project is a companion database to the Entrez
Genome database. It is a collection of both complete and incomplete
(in-progress) large-scale sequencing projects.
Chromosomes is the integration of three databases: NCBI Spectral
Karyotyping (SKY) / Comparative Genomic Hybridization (CGH) Database,
the NCI Mitelman
Database of Chromosome Aberrations in Cancer, and the NCI Recurrent
Aberrations in Cancer. The cytogenetic, clinical, and/or reference information
can be retrieved from this database.
Each Cluster of Orthologous
Groups of proteins (COGs) is a group of 3 or more proteins that are inferred
to be orthologs. COGs were created by comparing protein sequences encoded in
Gene is one of the gene-centered resources at NCBI. It supplies
key connections to the map, sequence, expression, structure, function,
citation, and homology data. It is the successor to LocusLink, with
a broader taxonomic scope, better integration with other databases in
NCBI, and enhanced options for query and retrieval by Entrez system.
