Final answer:
E. coli is a prokaryote and not a eukaryote, despite being a commonly studied bacterium.
Step-by-step explanation:
The statement that is NOT true of E. coli is A. E. coli is a model eukaryote.
E. coli is actually a prokaryote, not a eukaryote. It is a small, rod-shaped cell and can be grown in the laboratory. It is commonly found in the gut of humans and other vertebrates.
E. coli is a well-studied bacterium and is used as a model organism for various scientific experiments and research, but it is not a eukaryote.
