Genetic Engineering Flashcards
what’s the first stage of genetic engineering
the restrictive enzyme cuts out the useful section of the gene from the organisms DNA leaving sticky ends
what’s the second stage of genetic engineering?
the same restrictive enzyme is used to cut the plasmid leaving complementary sticky ends
what’s the third stage of genetic engineering?
The gene and plasmid are joined together using an enzyme called ligase
what’s the last stage of genetic engineering?
the plasmids are inserted back into bacteria. The bacterial cell multiplies
what is genetic engineering?
involves removing the gene of an organism and inserting it into the DNA of another organism to result in a desired characteristic
Benefits of GM
faster and more efficient
improves crop quality - reduce hunger
Disadvantages of GM
expensive
transfer of selected gene - what benefits one plant hurts another
