Episode guide
Genes & DNA: What Makes You... You
Inside almost every one of your cells is a curled-up letter written in a four-letter alphabet. This episode reads a little of it aloud, slowly.
The science, gently
- DNA uses just four letters, A, T, C, and G, to write the recipe for a whole person.
- Stretched out, the DNA in a single one of your cells would be about two meters long.
- You share half your recipe with each parent, and a surprising amount with a banana.
Wonder together
- Which parts of you feel most like each of your parents?
- If your cells carry a recipe, what do you think the rarest ingredient is?
- What would you write into your recipe, if you could add one line?
Tonight's calm-down
Every cell in you already knows what to do tonight: rest, repair, grow. You do not have to supervise. Close your eyes and let two meters of quiet instructions do their gentle work.
