While the mechanics and regulation of RNA synthesis share similarities between prokaryotes and eukaryotes, there are also several key differences between the processes in each type of organism.

Indicate whether each statement below describes transcription in prokaryotes or in eukaryotes.

Prokaryotic Transcription

Eukaryotic Transcription

Is a cytoplasmic process.

Is a nuclear process.

Produces RNA molecules that are chemically modified at the 3’ and 5’ ends to increase stability.

Is initiated by promoter binding of the $\sigma$ subunit of the RNA polymerase.

Is typically coupled to translation of the mRNA being produced.

Is catalyzed by one of three different RNA polymerases.
