Biologists at the University of California, San Diego have found another member in a new class of cellular motor proteins that rewind and seal together sections of the double-stranded DNA molecule that occasionally but perilously become unwound. Their discovery, which provides a promising new avenue for the development of drugs that kill cancer cells, is detailed in a paper published in this week's early online edition of the Proceedings of the National Academy of Sciences. The same...

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. "When your DNA gets stuck in the unwound position, your cells are in big trouble, and in humans, that ultimately leads to death" said Jim Kadonaga, a professor of biology at UCSD...


Word of the Day
callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
