Topic 4 - Genetic Engineering

Question 1

what’s the first stage of genetic engineering

Answer 1

the restrictive enzyme cuts out the useful section of the gene from the organisms DNA leaving sticky ends

Question 2

what’s the second stage of genetic engineering?

Answer 2

the same restrictive enzyme is used to cut the plasmid leaving complementary sticky ends

Question 3

what’s the third stage of genetic engineering?

Answer 3

The gene and plasmid are joined together using an enzyme called ligase

Question 4

what’s the last stage of genetic engineering?

Answer 4

the plasmids are inserted back into bacteria. The bacterial cell multiplies

Question 5

what is genetic engineering?

Answer 5

involves removing the gene of an organism and inserting it into the DNA of another organism to result in a desired characteristic

Question 6

Benefits of GM

Answer 6

faster and more efficient
improves crop quality - reduce hunger

Question 7

Disadvantages of GM

Answer 7

expensive
transfer of selected gene - what benefits one plant hurts another
