BLAST (Basic Local Alignment Search Tool) and ClustalW are both sequence alignment algorithms used in bioinformatics to align the sequences of interser, but they serve different purposes and are best suited for different scenarios. Here are the primary differences between them and their appropriate use cases:
BLAST: Best for quickly finding local regions of similarity between a query sequence and sequences in a large database. Ideal for sequence similarity searches, database annotations, and identifying homologous sequences.
ClustalW: Best for aligning multiple sequences globally to identify conserved regions and study evolutionary relationships. Ideal for phylogenetic analysis, identifying conserved motifs, and analyzing sequence conservation.
