MO640 - Multiple-choice question

In the matrix used to compute the local similarity between two sequences, where do we look for this similarity value and when do we stop the construction of an optimal alignment?

1. Look for the maximum in the entire matrix. Stop alignment construction when the first line or first column is reached.
2. Look for the maximum in the entire matrix. Stop alignment construction when a zero is found.
3. Look for the maximum in the last line and last column. Stop alignment construction when position (0,0) is reached.
4. Look for the maximum in the last line and last column. Stop alignment construction when the first line or first column is reached.
5. None of the above
