Answer:
See the answer below
Explanation:
The gene expression involves a series of steps that have to do with encoding the information in genes as mRNA - transcription - and the translation of the codes into proteins - translation.
The process of transcription and translation happens within the same space in prokaryotic cells. Since they have neither nuclei nor membrane-bound organelles, both transcription and translation happen in the cytoplasmic space of the cell simultaneously.
However, in eukaryotic cells, transcription happens in the nucleus because the DNA is located within it. Once this takes place, the mRNA produced is transported outside the nucleus into the cytoplasm where they engage with the ribosome and tRNA in a translation process.
