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.
The restriction endonucleases used in recombinant DNA work:
A) Always produce blunt ends. (No unpaired bases.)
B) Recognize sequences 4-6 bp long.
C) Cut the DNA outside the recognition sequence.
D) All of the above.
What are some of the impacts of biotechnology on crop plants in the United States? (Select all that apply.)
a. the development of pest-resistant crops
b. the development of transgenic crops
c. the development of nutritionally-enhanced crops
d. the development of herbicide-resistant crops
e. the spread of transgenes from genetically modified crops to wild plants
f. quicker identification of hazardous organisms in food
How can RFLP analysis be used to distinguish viruses?
Consider inductor wiring for the following questions.
(a) Why is it that inductors can have no insulation and input voltage doesn’t skip the loops to the output terminal?
(b) How does insulation affect an inductor?
Explain what happens at the atomic level.
