Detailed explanation-1: -In bioinformatics, BLAST (basic local alignment search tool) is an algorithm and program for comparing primary biological sequence information, such as the amino-acid sequences of proteins or the nucleotides of DNA and/or RNA sequences.

Detailed explanation-2: -The Basic Local Alignment Search Tool (BLAST) finds regions of local similarity between sequences. The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance of matches.

Detailed explanation-3: -Basic Local Alignment Search Tool (BLAST) The program compares nucleotide or protein sequences and calculates the statistical significance of matches. BLAST can be used to infer functional and evolutionary relationships between sequences as well as help identify members of gene families.

Detailed explanation-4: -Conclusion. Thus, since its creation, BLAST has become an essential tool for biologists. Its speed and sensitivity allow scientists to compare nucleotide and protein sequences to both single sequences and large databases.

Detailed explanation-5: -BLAST is a fast, heuristic approximation to the Smith–Waterman algorithm. An analytic theory describes the optimal scores of ungapped local alignments. The statistical parameters for BLAST’s gapped local alignments are precomputed by random simulation.
