This is a sentence of the lesson «The future of life: de-extinction, climate, coral and frozen zoos» of the biology 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 (rex, DNA), what happens, when and where, as Mova's frames read it from the tree.
