Bacterial gene expression

Bacterial genes and eukaryotic genes both code for proteins, but the processes involved are different.

In eukaryotes, translation occurs in the nucleus and only translation occurs in the cytoplasm.

Bacteria do not have nuclei. Both transcription and translation occur in the cytoplasm of the bacterium.

This means transcription and translation can occur simultaneously as there is no compartmentalisation of the two processes.

Bacterial gene organisation and gene expression are much simpler than eukaryotic gene organisation and gene expression; this reflects the relatively simple structure of bacteria.
