We consider rotating strings and D2-branes on type IIA background, whicharises as dimensional reduction of M-theory on manifold of G2 holonomy, dual toN=1 gauge theory in four dimensions. We obtain exact solutions and explicitexpressions for the conserved charges. By taking the semiclassical limit, weshow that the rotating strings can reproduce only one type of semiclassicalbehavior, exhibited by rotating M2-branes on G2 manifolds. Our furtherinvestigation leads to the conclusion that the rotating D2-branes reproduce twotypes of the semiclassical energy-charge relations known for membranes ineleven dimensions.Comment: LaTeX, 29 pages, no figures; V2:comments added; V3:no changes, to appear in JHE
