Final answer:
District courts do not hear cases based on the entire U.S. Code, but rather they have limited jurisdiction.
Step-by-step explanation:
No, district courts do not hear cases based on the entire U.S. Code, but rather they have limited jurisdiction. District courts are part of the federal court system in the United States and their jurisdiction is determined by Article III of the Constitution and specific legislation. They have the authority to hear cases involving federal law, disputes between states, and disputes between residents of different states, among other things.
