The most striking difference is that Saccharomyces cerevisiae (yeast) has a more complex cellular organization, including organelles such as the nucleus, mitochondria, and endoplasmic reticulum, which requires a more sophisticated system for targeting proteins to specific organelles. E. coli, being a prokaryote, lacks these organelles and thus has less need for such mechanisms.
