Which of the following does not describe local alignment algorithm?
swat32

Answer:

The answer is "Option a".

A score can be detrimental. When an element has a score below zero, it means, that the sequences up to this point have no correlations, that are set to zero and its effects the previous alignment is excluded. Thus, alignment can be further found in every position later in the calculation. and other options are incorrect that can be described as follows:
