Blast is one of highly used techniques in bioinformatics that is used for finding similar sequences in large data collected from NGS: Next generation of sequencing.
BLAST is a computer algorithm that is available for use online at the National Center for Biotechnology Information (NCBI) website, as well as many other sites. BLAST can rapidly align and compare a query DNA sequence with a database of sequences, which makes it a critical tool in ongoing genomic research.
