Includes the cleavage of double-stranded RNA to form small interfering RNA molecules (siRNAs) of 21-23 nucleotides. May also include amplification of the siRNA by RNA-directed RNA polymerase. production of siRNA involved in PTGS GO:0070919 production of siRNA involved in post-transcriptional gene silencing by RNA production of guide RNAs involved in RNA interference production of siRNA involved in gene silencing by small RNA production of siRNA production of siRNA involved in chromatin silencing by small RNA RNA interference, production of guide RNAs production of guide RNAs involved in chromatin silencing by small RNA RNA interference, production of siRNA Reactome:R-HSA-426486 production of siRNA involved in RNA interference chromatin silencing by small RNA, production of guide RNAs regulatory ncRNA processing
