Statement 1: Biosilk has already replaced nylon in parachute manufacture.
Passage: The new material, biosilk, which has been spun for the first time by researchers at DuPont, has an enormous range of potential uses in construction and manufacturing.
Statement 2: Lewis and Dorsch co-operated in the synthetic production of silk.
Passage: To recreate the material, scientists, including Randolph Lewis at the University of Wyoming, first examined the silk-producing gland of the spider. “We took out the glands that produce the silk and looked at the coding for the protein material they make, which is spun into a web. We then went looking for clones with the right DNA,” he says. At Dupont, researchers have used both yeast and bacteria as hosts to grow the raw material, which they have spun into fibers. Robert Dorsch, DuPont’s director of biochemical development, says the globules of protein, comparable with marbles in an egg, are harvested and processed.
