Question
On January 18,2002, in the Windsor Star, it was reported that a Montreal-area company had been able to produce spider silk in genetically engineered hamster and cow cells. The company, Nexia, calls the product "BioSteel". They are grow ing a herd of genetically altered goats which will soon begin producing the proteins in their milk. Determine whether the following portion of a coding DNA sequence, CCTGCTCCCCCGAGACCA, would provide dragline silk with toughness or with elasticity. Show your work and explain your reasoning.

"From Cows, Spider's Silk" In 1996 Equinox reported that two scientists were investigating spider dragline silk. This is the silk that a spider hangs from and uses to build the frame portion of its web. Spider silk can be as strong per unit weight as high-tensile steel; it can stretch more than nylon; and it is tougher than the Kevlar used in bullet-proof vests. It is hoped that synthetic spider silk can be produced and used to manufacture wear-resistant clothing, rust-free automobile panels and bumpers, artificial tendons and ligaments, and suspension-bridge cables. Lynn Jelinski, a biophysicist at Cornell University, proposed a model to explain dragline silk's strength and elasticity. She and her colleagues have shown how components of natural silk hang together. Each fibre consists of two alanine-rich crystalline proteins embedded in a glycine-rich protein polymer. According to their model, the protein polymer makes the fibre elastic and the two types of crystalline protein give it toughness. In 1990, University of Wyoming biochemist Randy Leis identified a gene linked to the production of prote ins in spider silk. This was the first step in allowing bioengineers to insert copies of the gene into bacteria, in hope of tuming the bacteria into microscopic spider silk protein factories.
