What is the difference between synthetic biology and genetic engineering?
Pigweed is an agile competitor for space in soybean fields. A genetically engineered soybean produces a toxin that can reduce the pigweed population in a field by 99% and is being considered for widespread distribution. As the genetic engineering company’s leading evolutionary biologist, craft an argument to convince the geneticists that their plan may fail to solve the pigweed problem in the long run.

B) Recognize sequences 4-6 bp long.
C) Cut the DNA outside the recognition sequence.
D) All of the above.
