Cloning/genetic Engineering (P1)

Question 1

Clone

Answer 1

An individual that has been produced by asexual reproduction and is genetically identical to one parent

Question 2

Taking cuttings

Answer 2

-stem taken off plant and dipped in rooting powder
-planted in another piece of soil
+quick and easy
Used for cloning plants

Question 3

Tissue culture

Answer 3

-take a small group of plant cells
-add to selected hormones
-makes tiny new plants
+guarantees required characteristics
Used for home and garden plants, preserving rare species

Question 4

Cloning adult cells (part 1)

Answer 4

A body cell is taken from sheep a and nucleus removed
Egg taken from sheep b and nucleus thrown away
Nucleus from a is put into empty egg of b

Question 5

Cloning adult cells (part 2)

Answer 5

• tiny electric shock divides egg to produce embryo with same genetic material as a
• embryo develops into ball of cells and inserted to sheep c
• Developed normally

Question 6

Embryo transplantation

Answer 6

• take sperm from best bull to fertilise eggs in uterus or lab
• fertilised eggs divide to form embryos of several cells
• embryo spilt into individual cells which form new embryos
• implanted with surrogate mother cells
• give birth to many cloned calves
