Transcription in Prokaryotes and Eukaryotes (With Diagram) In prokaryotic organisms transcription occurs in three phases known as initiation, elongation and termination. RNA is synthesized by a single RNA polymerase enzyme which contains multiple polypeptide subunits. In E. coli, the RNA polymerase has five subunits: two α, one β, one β' and one σ subunit (α 2 ββ'σ). This form is called the holoenzyme. Transcription, RNA Processing, and Translation - The Biology Primer Where bacterial transcription is initiated by a sigma protein, RNA Polymerases in eukaryotes require a group of proteins known as basal transcription factors. Like sigma in prokaryotes, once the basal transcription factors attach to the DNA, its respective RNA Polymerase attaches and transcription begins.

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.

Steps of Transcription From DNA to RNA - ThoughtCo The two main steps in gene expression are transcription and translation. Transcription is the name given to the process in which DNA is copied to make a complementary strand of RNA. RNA then undergoes translation to make proteins. The major steps of transcription are initiation, promoter clearance, elongation, and termination.
