Book 26, Question 35
How do labs make spider-silk-like fibers without spiders?
Spiders cannot be farmed like silkworms, because they attack each other when crowded.
So scientists copy the recipe instead. They put spider-silk genes into tiny living things such as bacteria or yeast, which then make silk protein in big tanks. The protein is spun into thread. Companies have made test jackets and ties from it, and doctors hope to use such fibers for strong, gentle stitches.
