Transcription is a process by which the genetic information present in the DNA is copied to an intermediate molecule (RNA). The sequence in the RNA is complementary to that of the gene which is transcribed and thus the RNA retains the same information as the gene itself. Transcription is a universal process in the living word and it occurs both in prokaryotes and eukaryotes. Even though the overall process of transcription is similar in both prokaryotes and eukaryotes, there do exists some fundamental differences between these groups.
This post summarizes the overall similarities and differences between the Prokaryotic and Eukaryotic transcription in a detailed but easy way.
Similarities between prokaryotic and eukaryotic transcription
1. In both groups DNA acts as the template for RNA synthesis
2. In both groups transcription produces RNA molecule
3. Chemical composition of transcript is similar in both groups
4. Transcription is facilitated by the enzyme RNA polymerase in both groups
5. In both groups, one strand of the DNA duplex acts as the template
