When the Gap fill is at the start of the sentence, the correct answer starts with a capital. Sometimes a term has capitals on other places like EcoR1. However, the evaluation in those cases is not case sensitive.
When the user hits the 'Show Answers' the correct answer appears without the capitals: all lower case. But the keyword I entered had capitals, which I would like to show, though I do not mind when the user does not enter it that way.
