This approach is to generate nonnatural double-stranded miRNA-like RNA fragments. ** This is a software tool to create a scrambled sequence as negative control for your siRNA experiment. The sequences obtained from the sequence extraction step are used as input to three algorithms for the prediction of the miRNA binding sites (). The aim of this work is to consider various analyzing scenarios in the identification of miRNA. When one types in an oligo sequence, this internet tool returns the complement sequence, length, GC content, melting temperature, molecular weight, molecular. While multi-target RNAi has been demonstrated as a proof of concept ( 22 ), a systematic analysis of artificial miRNAs designed to target specific genes has not been. For each tested sample, only miRNA candidates with positive miRDeep2 score and > 50 unnormalized read counts were used for further analysis.
