Genetic engineering

Question 1

What is genetic engineering?

Answer 1

It is the transfer of genes

Question 2

What do enzymes do the enzymes do to the gene and chromosome?

Answer 2

It cuts the gene from the chromosome

Question 3

What does insulin do?

Answer 3

Controls sugar levels

Question 4

What are the steps for genetic engineering?

Answer 4

Find the gene from the DNA . Once the gene has been found you need to cut it out using special enzymes called restriction enzymes. Cut the bacterial plasmid using the same enzyme. Insert the designed gene into the cut bacterial plasmid. Insert the new modified plasmid into bacterium by giving it an electric shock and let the bacteria divide to produce human insulin.

Question 5

What will farmers do to kill insects off their crops?

Answer 5

Spray chemicals

Question 6

Describe genetic engineering in insect resistance?

Answer 6

take a cell from a plant in the early development, remove one of the chromosomes and the gene then offers insect resistance. Next put the gene into the chromosomes using enzymes and the gene with the chromosome can be placed back into the plant cell.

Question 7

What are the plants called that have been modified called?

Answer 7

Genetically modified crops or GM crops

Question 8

Give a disadvantage for GM crops?

Answer 8

Could kill other important insects or even animals or humans
