PPT-Local alignments & BLAST

online and offline WenDar Lin Bioinformatics core IPMB wdlingatesinicaedutw Preface When we are talking about sequence similarity we usually are talking about local alignments NCBI BLAST is one of the most famous local alignment programs where almost everyone has ever used it.

Follow the advice of the station helper to find out if a structure makes a difference and why so you can make the best rocket based on the distance it travels while maintaining a fairly straight path.
