Below the calm, ordered exterior of a living organism lies microscopic chaos. Our cells are filled with molecular machines, which, like tiny ratchets, transform random motion into ordered activity, and create the ΓÇ£purposeΓÇ¥ that is the hallmark of life. Tiny electrical motors turn electrical voltage into motion, nanoscale factories custom-build other molecular machines, and mechanical machines twist, untwist, separate and package strands of DNA. The cell is like a cityΓÇöan unfathomably, complex collection of molecular workers creating something greater than themselves.
