In forming the negative sentences, "does not" is used to negate the action for singular subjects, while "do not" is used for plural subjects. In forming interrogative sentences, the auxiliary "does" is placed at the beginning for singular subjects, and "do" is used similarly for plural subjects. The main verb remains in its base form in both negative and interrogative transformations.
