Methods and compositions for enhancing the efficacy and specificity of RNAi

A method of enhancing the efficacy of an siRNA duplex, or promoting entry of an antisense strand of an siRNA duplex into a RISC complex, the siRNA duplex comprising the antisense strand and a complementary strand, the strands each having 5' and 3' ends, the method comprising enhancing the asymmetry of the siRNA duplex by lessening the base pair strength between the 5' end of the antisense strand (AS 5') and the 3' end of the sense strand (S 3') relative to the base pair strength between the 3' end of the antisense strand (AS 3') and the 5' end of the sense strand (S 5'), such that efficacy of the siRNA duplex is enhanced, or entry of the antisense strand into the RISC complex is promoted.
