Transcription - Elongation
One strand of DNA serves as the template for RNA synthesis, but multiple rounds of transcription may occur so that many copies of a gene may be produced.

Transcription - Termination
Termination is the final step of transcription. Termination results in the release of the newly synthesized mRNA from the elongation complex.

Transcription in Prokaryotes Versus Eukaryotes
There are significant differences in the process of transcription in prokaryotes versus eukaryotes.

Transcription - Pre-Initiation
The first step of transcription is called pre-initiation. RNA polymerase and cofactors bind to DNA and unwind it, creating an initiation bubble. This is a space that grants RNA polymerase access to a single strand of the DNA molecule.

Transcription - Initiation
The initiation of transcription in bacteria begins with the binding of RNA polymerase to the promoter in DNA. Transcription initiation is more complex in eukaryotes, where a group of proteins called transcription factors mediate the binding of RNA polymerase and the initiation of transcription.

Transcription - Promoter Clearance
RNA polymerase must clear the promoter once the first bond has been synthesized. Approximately 23 nucleotides must be synthesized before RNA polymerase loses its tendency to slip away and prematurely release the RNA transcript.

Steps of Transcription From DNA to RNA
Transcription is the name given to the chemical synthesis of RNA from a DNA template. In other words, DNA is transcribed in order to make RNA, which is then decoded to produce proteins.
