The Nucleotide database is a collection of sequences from several sources, including GenBank, RefSeq, TPA and PDB. Genome, gene and transcript sequence data provide the foundation for biomedical research and discovery.
8 Δεκ 2022 · Search GenBank for sequence identifiers and annotations with Entrez Nucleotide. Search and align GenBank sequences to a query sequence using BLAST (Basic Local Alignment Search Tool). See BLAST info for more information about the numerous BLAST databases.
You can use Entrez query syntax to search a subset of the selected BLAST database. This can be helpful to limit searches to molecule types, sequence lengths or to exclude organisms. more...

The Basic Local Alignment Search Tool (BLAST) finds regions of local similarity between sequences. The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance of matches.
5 Αυγ 2024 · Nucleotide records have over 30 types of elements or fields, most of which are directly searchable. Fields in Nucleotide records include those for accession numbers, sequence features, sequence source, and associated journal literature. Field tags, represented as field names in brackets, can be used in a Nucleotide query to search these fields.
The database is preset on this page to the nucleotide sequences for Grey Whale genome assembly (mEscRob2.pri GenBank assembly [GCA_028021215.1]) that contains assembled chromosome sequences and component sequences.
