BLAST is one of the most widely used bioinformatics programs for sequence searching. [4] It addresses a fundamental problem in bioinformatics research. The heuristic algorithm it uses is much faster than other approaches, such as calculating an optimal alignment.
The program compares nucleotide or protein sequences to sequence in a database and calculates the statistical significance of the matches. This chapter first provides an introduction to BLAST and then describes the practical application of different BLAST programs based on the BLAST Quick Start mini-course (www.ncbi.nlm.nih.gov/Class/minicourses).
Mar 17, 2014 · BLAST for beginners introduces students to blastn, a commonly used tool for comparing nucleotide sequences (DNA and RNA). This popular tutorial shows how to do a blast search with a nucleotide sequence, highlights information in the search results, and shows how to interpret the E value and alignment scores.
