BLAST (Basic Local Alignment Search Tool) is a widely used bioinformatics tool for comparing DNA or protein sequences against a database of other sequences. It helps in identifying the homologous sequences, finding structural and functional similarities among the sequences and assigning a function to the isolated sequence. Hence, it is the best tool to be used in this scenario.
