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.
