# Molecules: when atoms join up, sentence 16

<!-- .ven lang=en -->
A water molecule has 3 atoms, a sugar molecule 45, and the DNA in one of your cells has billions; stretched out it would be about two metres long, but it is extremely thin and tightly coiled and packed.

<!-- .vintro -->
**Who acts:** water molecule, DNA · **What happens:** have, stretch out, be · **To what, where:** 3 atoms, billions

<!-- .vabout -->
This is a sentence of the lesson «Molecules: when atoms join up» of the chemistry course of Mova's primary school. The page gives its syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause: who acts (water molecule, DNA), what happens, when and where, as Mova's frames read it from the tree.
