Sequence Alignments Consider the sequences S1 = TACGGGTAT a

Sequence Alignments: Consider the sequences S1 = TACGGGTAT and S2 = GGACGTACG.Assume that the match score is 1, mismatch score is -1, and gap penalty is d = -2.a. Find an optimal global alignment b. Final an optimal local alignment). Scoring Alignments: Given the following alignments of three sequences, what isthe sum-of-pairs score? Assume that the scoring system: match score = 1,mismatch score = -2, gap score = -4 (20 points). ACCTCTGTC AC -TGTAAC ACCTGT- AC
