Blast (Basic Local Alignment Search Tool) Explanation:

BLAST (basic local alignment search tool) is an algorithm that is used for comparing the primary biological sequence information such as nucleotides of DNA/RNA sequences or amino-acid sequences of proteins. The BLAST search allows the researcher to compare a query sequence with a library of sequences in the database, and it helps to identify the sequences which resemble the query sequence beyond a certain threshold.
