Gene Regulation - Eukaryotic Cells
... Prokaryotic regulation is different from eukaryotic regulation. 1. Eukaryotic cells have many more genes (23,700 in human cells) in their genomes than prokaryotic cells (average 3000). 2. Physically there are more obstacles as eukaryotic chromatin is wrapped around histone proteins. ...
