Intermediate Topic 31 of 51 Emerging & Frontier Topics
Sequence Alignment
Comparing DNA or protein strings.
How it works
Needleman-Wunsch (global) and Smith-Waterman (local) use dynamic programming with substitution scores and gap penalties; BLAST uses heuristics to search huge databases quickly.
Where it is used
Comparing DNA and proteins.
Common pitfall
Scoring matrix choice (BLOSUM) affects results.
Where it fits in the course
Sequence Alignment is topic 31 of 51 in Emerging & Frontier Topics, rated Intermediate. It follows Bioinformatics. The next topic is Computational Neuroscience.
