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.
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.
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.
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...
Search and align GenBank sequences to a query sequence using BLAST (Basic Local Alignment Search Tool). BLAST searches Nucleotide, dbEST, and dbGSS independently; see BLAST info for more information about the numerous BLAST databases.
The Basic Local Alignment Search Tool, or BLAST, is the most widely used program for such searches. When searching a nucleotide database, BLAST has the ability to translate the database sequences on the fly to compare coding regions.
16 Ιαν 2022 · The Basic Local Alignment Search Tool, or BLAST, is the most widely used program for sequence similarity searches. In addition to comparing nucleotide sequences, BLAST can also translate nucleotide sequences into all six reading frames at run time in order to compare protein coding regions.
