a. Read five different protein sequences from any public repository and store them in five different files in your hard drive.
b. Using nested loop, read each file with following combination and apply global pairwise alignment on sequences. For scoring, use BLOSUM100, BLOSUM62 and BLOSUM45 scoring matrix:
like: file1- file2, file1-3, file1- file4, file1- file5, file2- file3, file2- file4, file2- file5, file3-file4, file3- file5, file4- file5
c. Show histogram of all above scores for each BLOSUM matrix.
