What you will learn in What the molecule does

1. 1. Proving it is DNA

   Three experiments across twenty-four years, each as an elimination.

2. 2. The structure, and what it implies

   Why grooves matter, shown by a protein reading bases through one.

3. 3. Copying

   Predicting three models, then seeing which one the experiment matches.

4. 4. Transcription

   Which strand is copied, and what the wrong choice produces.

5. 5. The code, and translation

   Counting how many mutations the code absorbs, position by position.

6. 6. Mutation, and what a gene is

   One base traced to a protein, a structure and a disease.

7. 7. Reading a real genome

   Why three reference databases disagree about how many genes a human has.
