A typical protein-coding gene is first copied into RNA as an intermediate in the manufacture of the final protein product.:6.1 In other cases, <answer>the RNA molecules</answer> are the actual functional products, as in the synthesis of ribosomal RNA and transfer RNA. Some RNAs known as ribozymes are capable of enzymatic function, and microRNA has a regulatory role. The DNA sequences from which such RNAs are transcribed are known as non-coding RNA genes.
In some cases, what are the actual functional products?
the RNA molecules
