E.1 Sequence Alignment (12 pts) a) Draw the matrix for an optimal sequence alignment of at with tac . You may wish to represent your matrix as a directed graph with nodes and draw edges between the nodes. Use letters as indices into the matrix/graph. Use gap penalty 8=2 and a mismatch penalty of a=3. As part of your answer, include the alignment that your matrix/graph represents. b) Repeat part a) changing the gap penalty to d=1. c) Based on your answer to the above parts are sequence alignments always unique?
