Question (select most suitable option)

  Which of the following doesn't describe local alignment?
A local alignment aligns a substring of the query sequence to a substring of the target sequence
A local alignment is defined by maximizing the alignment score, so that deleting a column from either end would reduce the score, and adding further columns at either end would also reduce the score
Local alignments have terminal gaps
The substrings to be examined may be all of one or both sequences; if all of both are included then the local alignment is also global
