Compare & Contrast Transcription in Eukaryotes & Prokaryotes.


  • A lot of the pioneering work on transcription was carried out in prokaryotes, most notably in the bacteria E. Coli.

  • Prokaryotes have a single RNA polymerase.

  • Eukaryotes have 3 different RNA polymerase.

  • Transcription in eukaryotes is more complex.

  • Eukaryotic RNA polymerase cannot initiate transcription by themselves, they need the help of a set of proteins called the basic transcription factors.


  • The enzyme that carries out transcription is called RNA polymerase, it consist of 4 polypeptides.

  • Transcription can be divided into 3 phases: initiation, elongation, and termination.
