Interpretation Introduction

Interpretation:

On performing two BLAST searches, one on the peptide sequence FIDPWE and another on the sequence KRTIAAVNSPLLEVATY, the search that will give alignments with 'expect scores" closer to one should be predicted.

Concept Introduction:

BLAST stands for Basic Local Alignment Search Tool. A bioinformatic tool it is an algorithm which can compare primary biological sequence information (nucleotide or amino acid sequence) with a database or a library of sequences. It result is then used to identify similar sequence based on a certain threshold.
