Multiple Sequence Alignments Sequences are aligned so as to bring the greatest number of single characters into register If we include gaps, mismatches then even dynamic programming becomes limited to 3 sequences unless they are very short.. need an alternative approach Why?Multiple Sequence Alignments • Sequences are aligned so as to bring the greatest number of single characters into register. • If we include gaps, mismatches, then even dynamic programming becomes limited to ~ 3 sequences unless they are very short….need an alternative approach… Why?
