Analogy
DNA and genes is like a living system solving a small survival problem: each part has a job, and the answer depends on how those jobs connect.
Why now: An analogy helps when the definition feels abstract.
Do this: Match each part of the analogy to the science idea.
Learn it
DNA is a polymer that carries genetic information.
