Nucleotide. 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.
Allele Frequency Aggregator (ALFA) provides the Database of Single Nucleotide Polymorphisms (dbSNP) with allele frequency data for 200K subjects from the Database of Genotypes and Phenotypes (dbGaP). ALFA adheres to the Findable, Accessible, ….
Nov 28, 2023 · 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.
Select the sequence database to run searches against. No BLAST database contains all the sequences at NCBI. BLAST databases are organized by informational content (nr, RefSeq, etc.) or by sequencing technique (WGS, EST, etc.). more...
Dec 8, 2022 · Access to GenBank. There are several ways to search and retrieve data from GenBank. 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).
NCBI Nucleotide. The NCBI Nucleotide Database is a database of nucleic acid sequences. These sequences come from laboratories around the world that submit their data to one of a set of repositories, including GenBank, which is maintained by NCBI.
Mar 21, 2024 · The program compares nucleotide or protein sequences 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.
