DNA transcription is a process that involves transcribing genetic information from DNA to RNA. The transcribed DNA message, or RNA transcript, is used to produce proteins. DNA is housed within the nucleus of our cells.It controls cellular activity by coding for the production of proteins.NA Transcription. 1  RNA Polymerase Binds to DNA. 2  DNA is transcribed by an enzyme called RNA polymerase. 3  Specific nucleotide sequences tell RNA polymerase where to begin and where to end. 4  RNA polymerase attaches to the DNA at a specific area called the promoter region. 5  Elongation.
