SCIENTISTS SPEAK ABOUT DNA

"[The instructions within the DNA of the cell] if written out, would fill a thousand 600-page books. Each cell is a world brimming with as many as two hundred trillion tiny groups of atoms called molecules . . Our 46 chromosome `threads' [in one DNA molecule] linked together would measure more than six feet. Yet the nucleus that contains them is less than four ten-thousandths of an inch in diameter."—*Rick Gore, "The Awesome Worlds Within a Cell," National Geographic, September 1976, pp. 357-358, 360.
