"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. " - Small rna synthesis
