[Campbell Biology P.887] Which of the following statements about glyphosate and glyphosate-r... | Practice Question

Which of the following statements about glyphosate and glyphosate-resistant crops is supported by the information in the text?

  • A: Glyphosate works by interfering with the reproductive cycles of weeds, preventing seed production.
  • B: Glyphosate-resistant crops were developed by splicing a mutated bacterial gene into plant genomes.
  • C: The widespread use of glyphosate has led to a decrease in overall weed populations globally.
  • D: Glyphosate is known to positively impact beneficial gut bacteria in animals and humans.

Explanation

The text states: 'Researchers discovered a bacterial strain that had undergone a mutation in the gene encoding this enzyme that rendered it glyphosate resistant. When this mutated bacterial gene was spliced into the genome of various crops, these crops also became glyphosate resistant.' This directly supports option B.
