   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).
