We examine the effect of d-wave symmetry on zero-bias anomalies in normal-superconducting tunnel junctions and phase-periodic conductances in Andreev interferometers. In the presence of d-wave pairing, zero-bias anomalies are suppressed compared with the s-wave case. For Andreev interferometers with aligned islands, the phase-periodic conductance is insensitive to the nature of the pairing, whereas for nonaligned islands, the nature of zero-phase extremum is reversed.
