NEW YORK, Sept 26 - Mitsubishi Rayon of Japan said Tuesday it had developed a technology to manufacture DNA chips that could reduce manufacturing costs by 90 percent, the Agence France-Presse reported from Tokyo.

" We have developed the technology to manufacture DNA chips," the AFP cited Koji Yamazaki, a spokesman for Japan's largest acrylic fiber maker, as saying.

" The company plans to reduce DNA chip manufacturing costs to less than a tenth of conventional manufacturing procedures."
