Comparison of Eukaryotes and Prokaryotes

The contrast between eukaryotes and prokaryotes is striking.

Figure 1 – Complex eukaryotic transcription & translation (left) versus streamlined bacterial transcription & translation (right). While bacterial transcription & translation can’t be truly described as simpler in any absolute sense (for they have more functions going on simultaneously at any given time and are in that way doubly complex as compared to eukaryotes), the process is definitely much-streamlined and has completely done away with complex steps.
