Transcription eukaryotic versus prokaryotic

FIGURE 11.24 The properties of mRNA molecules in prokaryotic versus eukaryotic cells during transcription and translation. 

Tab. 13.1 Transcription factors under the control of RNI. Selected examples for the regulatory impact of RNI on prokaryotic and eukaryotic transcription factors. In a very simplistic way activation versus inhibition by RNI are indicated.

There are also inhibitors that affect enzyme synthesis. Inhibitors of transcription (e.g., dibromothymoquinone [DBMIB]) and inhibitors of translation (e.g., cyclo-heximide [CHX]) are available but these are not specific to particular enzymes. In addition, because protein synthesis takes place within the chloroplast and mitochondrion in eukaryotes, prokaryotic protein synthesis inhibitors (e.g., chloramphenicol [CAP]) may be necessary to distinguish prokaryotic versus eukaryotic activity (e.g., Segovia and Berges, 2005).
