B6: Quiz 11
1)
a)
i) Genetic engineering uses vectors. An example of a vector used in genetic engineering is a plasmid. What is a plasmid and where are plasmids usually found?
ii) In addition to plasmids, what is another vector that can be used in genetic engineering?
b) Genetic engineering involves two different enzymes. What are the names of these enzymes and what do each of the enzymes do?
c) What does recombinant DNA mean?
2) Describe the steps involved in genetically engineering bacteria so that the bacteria produce human insulin.
3) Give 3 other uses of genetic engineering. Do not say genetically engineering bacteria so that they produce human insulin.
4)
a) What does the GM in GM crops stand for?
b) Give 3 ways that we can genetically engineer crops. Don’t say anything to do with making crops resistant to herbicides.
c) Herbicides are sometimes sprayed on crops.
i) What are herbicides and what do they do?
ii) We can create GM crops that are resistant to herbicides. Why would herbicide resistant GM crops be useful for farmers?
iii) Some scientists are concerned about the effect that herbicide resistant GM crops will have on weeds. What are their concerns?
d) Give 2 benefits of GM crops.
5) Apart from the concerns in question 4 c iii, give one other concern that some individuals have with genetically engineered food.
