WebTo understand how gene expression is regulated, we must first understand how a gene becomes a functional protein in a cell. The process occurs in both prokaryotic and eukaryotic cells, just in slightly different fashions. Because prokaryotic organisms lack a cell nucleus, the processes of transcription and translation occur almost simultaneously.
