“We've been tinkering with nature for tens of thousands of years - look...” — Frances Arnold Quote

“We've been tinkering with nature for tens of thousands of years - look at a poodle! So we've created all sorts of organisms and biological things that wouldn't be here were it not for us.”

“Engineering the biological world was even more interesting than engineering the mechanical world.”

“Silicon-based life on Earth doesn't make sense, but perhaps it would in some totally different environment.”

“Ultimately, biological phenomena involve molecules, and understanding them involves understanding the underlying chemistry. In my opinion, this is a particularly exciting area of chemistry.”

“The first experiments on the biological properties of radium were successfully made in France, with samples from our laboratory, while my husband was living.”

“As the Industrial Age is drawing to a close, I think that we're witnessing the dawn of the era of biological design.”
