Life stores information physically

What will you explore?

Watson & Crick, 1953

Life stores information physically.

How does it work?

Watch a 90-second cinematic explanation, or explore a story that pauses so you can change its central mechanism. Inspect the source evidence, compare outcomes and resume the narration. This free Lesson Worlds adaptation needs no account or download; younger learners may want help from a parent or teacher.

Inside the cinematic story

1. A shape with a secret.

   Structure can constrain information.

2. Two chains. Opposite directions.

   Backbones outside. Paired bases inside.

3. The partners are specific.

   A ↔ T G ↔ C

   Take control: Which complement does the DNA rule specify? A · G

4. Separate. Then complement.

   Each strand specifies its complement.

5. A proposal, not the whole process.

   A structural argument with experimental context.

6. Information has a physical form.

   Explore the rule that links the strands.

Discuss the evidence

Before starting, explain what you think this claim means: Life stores information physically. After exploring, choose one stage above and describe what its model helps you see. Separate what you observed in the adaptation from what the original researchers measured.

Read the original publication for its methods, evidence and limitations. Ask which part of the explanation the interactive model leaves out, and what additional evidence you would need to test the claim yourself.

Schematic molecular geometry. The 1953 paper proposed a structure and suggested a copying mechanism; this animation does not show the full replication machinery. Read the accompanying Franklin–Gosling and Wilkins research for experimental context.
