Application/Retake Class and DAT?

I am graduating with a 3.47 GPA as it went down from a 3.5 because of a bad grade in an upper level science class last semester of senior year. That was the worst I have done in any class and am planning on retaking it. However, I would not get the transcript for that specific retake until late August and I am planning on applying to dental schools by late June and retake my DAT also in mid July. Would it be wise to retake this upper level science course as it is not a requirement? I just do... Application/Retake Class and DAT?
