miRNA molecules are produced from transcribed noncoding regions. These tiny molecules are observable in both prokaryotes and eukaryotes and were first discovered in C. elegans. The main function of miRNA is to inhibit translation by attaching to target mRNAs. siRNAs arise from viral infections and bind to RNA to degrade it, in a process referred to as silencing.
