it is obvious that because of the degree of complexity resulting from the existence of numerous compartments and membrane systems , the development of a genetic programme in a eucaryote cell requires not only the transcription of specific genes and translation in the cytoplasma of the resultant messenger rna , but also the activity of mechanisms which ensure that each polypeptide reaches the site of its function , which may be in the cytosol , in a membrane , or in the luminal cavity of an organelle .
