Verified step by step guidance

Understand that both miRNAs (microRNAs) and siRNAs (small interfering RNAs) are types of small non-coding RNAs involved in gene regulation through RNA interference pathways.

Recognize that both miRNAs and siRNAs are initially transcribed as longer RNA precursors that require processing to become functional small RNA duplexes.

Identify the enzyme responsible for processing these precursors: the Dicer enzyme, which cleaves the longer RNA molecules into short double-stranded RNA fragments typically around 20-25 nucleotides in length.

Note that transcription by RNA polymerase III is not common to both, as miRNAs are usually transcribed by RNA polymerase II, and siRNAs can originate from various sources including exogenous double-stranded RNA.

Understand that neither direct incorporation into the ribosome nor polyadenylation at the 3' end is a step shared by both miRNA and siRNA processing pathways.
