Consider the following scoring scheme for DNA sequences. The score of a match is +5, the score of a mismatch between A and G, since they are both purines, is -1, similarly the score of a mismatch between C and T is also -1 since they are both pyrimidines, and the score of other mismatches is -4. The gap penalty is -2.
a. Find an optimal semi-global alignment of the sequences:
Sequence 1: AAGTTCGT
Sequence 2: CAGTCCT
b. Find an optimal local alignment of the sequences:
Sequence 1: AGTGGCATT
Sequence 2: TGTCACGT
note : in a. first row in the matrix should indicates the valeus of -2,5,3,1,-1,-2,-2 so please make sure of ur solution !
