Consider the following alignment of two DNA sequences:

                            AGTAAC

                            AA_ _AC

Assuming an affine gap scoring scheme of an identity matrix for substitution, a gap initiation penalty of 1 and a gap extension penalty of 0.1, the score of the alignment is _________
