WebThe Importance of Small RNAs. Small RNAs play a major role in the post-transcriptional regulation of gene expression. Though RNAi was initially discovered in nematodes and plants, RNA-mediated regulation is widely found in eukaryotic organisms, and similar small RNA guided regulatory pathways appear to be operative in prokaryotes. Eukaryotic ... WebSynthesis of RNA is usually catalyzed by an enzyme— RNA polymerase —using DNA as a template, a process known as transcription. Initiation of transcription begins with the binding of the enzyme to a promoter sequence in the DNA (usually found "upstream" of a gene). The DNA double helix is unwound by the helicase activity of the enzyme.
