Puffs

puffs

(Science: molecular biology) Expanded areas of a polytene chromosome. at these areas the chromatin becomes less condensed and the fibres unwind, though they remain continuous with the fibres in the chromosome axis.

A puff usually involves unwinding at a single band, though they can include many bands as in balbiani rings. Puffs represent sites of active rNA transcription. The pattern of puffing observed in the larvae of drosophila, in different cells and at different times in development provides possibly the best evidence that differentiation is controlled at the level of transcription.

Origin of life

... but from what we've seen so far it can be a naturalistic explanation(because it breaks no laws of physics, chem etc...) that doesn't require any puffs of smoke or suspension of natural laws. How do you know God doesn't work through natural law? What you're saying is that "science" excludes ...
