"Global sequence alignments"

You are given two sequences AGATTAC and AGTTAC. Assume a match score of 1, a gap penalty of 3 and a substitution score of -1. Using these scores, obtain the global alignment of these two sequences manually in the following two steps:

Fill in the entries of the F matrix by applying the recurrence relationship for global alignment to these sequences. Please show the back pointers to the matrix entry/entries that give you the maximal score for any entry.

Apply the trace back procedure to obtain an optimal alignment. If there are multiple possible alignments, please show all of them along with their traceback paths.

Draw out the alignments on paper and include the image in your assignment repository. Please type the alignments immediately following.
