In prokaryotes both transcription and translation occur in the cytoplasm due to the absence of nucleus. In eukaryote transcription occurs in the nucleus and translation occurs in ribosomes present on the rough endoplasmic membrane in the cytoplasm.
Regulation of transcription in eukaryotes is a result of the combined effects of structural properties (how DNA is packaged) and the interactions of proteins called transcription factors. The most important structural difference between eukaryotic and prokaryotic DNA is the formation of chromatin in eukaryotes.pecifically, gene expression is controlled on two levels. First, transcription is controlled by limiting the amount of mRNA that is produced from a particular gene. The second level of control is through post-transcriptional events that regulate the translation of mRNA into proteins.
