The dangling nucleotides are very important for the RNA interference (RNAi). We investigate the effect of the dangling end on both the thermodynamic property of the RNA helix and efficiency of gene regulation in RNAi pathway. The result indicates that the four dangling adenines, which are more stable than two or three dangling residues, is not suitable for the RNAi efficiency.
