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...
shotgun data and 16 million 'reads' of shredded GenBank data from other human genome projects (Nature 2001. 409:860-921). It relied on Celera's paired reads and BAC end reads from GenBank for long range order and orientation. See Istrail et al (2004).

This problem demonstrates how to use BLAST to find human sequences in GenBank that can be amplified with a particular primer pair. Access the nucleotide–nucleotide BLAST page (by clicking on the Nucleotide–nucleotide BLAST link).
BLAST es el acrónimo de Basic Local Alignment Search Tool. Fué desarrollado por Altschul en 1990 y es el algoritmo mas empleado por el NCBI. La principal característica del BLAST es su velocidad, pudiendo tomar pocos minutos cualquier búsqueda en la totalidad de la base de datos.
