Webb3 jan. 2024 · Eukaryotic Post-transcriptional Regulation After RNA is transcribed, it must be processed into a mature form before translation can begin. This processing after an RNA molecule has been transcribed, but before it is translated into a protein, is called post-transcriptional modification. WebbRegulation of Gene Expression in Eukaryotes. Gene is a part of DNA that specifies a protein/RNA. All the proteins/RNA are not required by the cell all the time. Some proteins are required at some time and yet other proteins are required at another time.
