The enzyme that unwinds DNA for replication or manufacture can spin up to 10,000 times a minute.

"DNA helicase travels ahead of the replication fork, continuously opening and unwinding the DNA double helix to provide the template needed by the DNA Polymerase. With a rotational speed of up to 10,000 rotations per minute, the helicase rivals the rotational speed of jet engine turbines.'

Talk about a nanomachine!!
