Two biologists at the University of California, San Diego have discovered the first of a new class of cellular motor proteins that "rewind" sections of the double-stranded DNA molecule that become unwound, like the tangled ribbons from a cassette tape, in "bubbles" that prevent critical genes from being expressed.
