In bioinformatics, the term ‘BLAST’ refers to
-
- database retrieval tool
- computational tool for sequence homology searching and alignment
- computational tool to view genomic sequences
- computational tool to view protein structures
Correct Option: B
In bioinformatics, Basic Local Alignment Search Tool, or BLAST, is an algorithm for comparing primary biological sequence information, such as the amino-acid sequences of different proteins or the nucleotides of DNA sequences. A BLAST search enables a researcher to compare a query sequence with a library or database of sequences, and identify library sequences that resemble the query sequence above a certain threshold.
