The herbicide glyphosate is not harmful to humans because humans
A) have an enzyme that breaks down glyphosate.
B) lack the ability to make aromatic amino acids.
C) have unique restriction enzymes.
D) lack a binding site for the Bt protein.
Much of the technology for producing GM foods is owned by corporations, which seek to maintain intellectual ownership of their creations. As one example, Monsanto Corporation requires farmers to sign contracts for glyphosate-tolerant soybeans that prevent the farmers from saving seed for replanting the next year. The company has aggressively brought suit against violators. On the one hand, companies need to be able to profit from their products, and the development costs of GM foods are enormous. On the other hand, in many highly populated regions of the world, people who face famine when their crops fail simply cannot afford to pay the price of seeds every year. How would you want to see this challenging issue handled?
