global DNA alignment
Controls
Presets
The Needleman-Wunsch algorithm finds the optimal global alignment of two sequences by dynamic programming, filling a scoring matrix and tracing back the best path. It is the foundation of bioinformatics — comparing genes, proteins, and genomes. The heatmap shows the accumulated score matrix.

Governing equation
Reading this result: Low similarity: only 0% of columns match (score 0). The optimal alignment leans on -2-penalty gaps and mismatches, so the sequences share little common structure.
