Gene expression in eukaryotic cells is regulated by repressors and also by transcriptional activators. Bacterial gene expression occurs within the cytoplasm of a cell due to the lack of a defined nucleus.
Bacterial gene expression (both transcription and translation) occurs within the cytoplasm of a cell due to the lack of a nucleus; therefore, the DNA is freely located within the cytoplasm. Eukaryotic gene expression takes place in the nucleus (transcription) and cytoplasm (translation) both.
Gene expression occurs in two essential steps that are : transcription and translation. In bacteria, these two processes are tightly coupled in time and space, and thus are highly regulated.
