Pairwise Sequence Alignment (global sequence alignment) Global alignments which attempt to align every residue in every sequence are most useful when the sequences in the query set are similar and of roughly equal size. (This does not mean global alignments cannot start and/or end in gaps.) A general global alignment technique is the
Implementation of a DNA sequence alignment algorithm. Time and Space Complexity O(nm) where n and m are the lengths of the sequences. Background Strands of DNA are made up of molecules called nucleotides of which there are four types Adenosine (A) Thymine (T) Cytosine (C) annd Guanine (G). Our genome is made up of a long sequence of
These are both dystrophin isoforms but the first sequence is missing about 100 residues starting at residue 948 (some exons have been spliced out of the corresponding mRNA). A global algorithm returns one alignment clearly showing the difference a local algorithm returns two alignments and it is difficult to see the change between the sequences.
