3. Genetic engineering: Cloning
Cloning - producing genetically IDENTICAL organisms
Begin and end with the same number of chromosomes.
Begin and end with the same type of genes.

4. Cloning animals: Dolly the sheep
First mammal to be cloned from a somatic (BODY) cell (taken from the udder)
Other species cloned: horses, bulls, cows, pigs, and mice.

5. Cloning Steps

6. Learning check
Tissue taken from a black mouse was enucleated. The resulting nuclei were then put inside the enucleated egg from a white mouse. What color would the baby mice be?

BLACK

8. Learning check
Monozygotic (identical) twins are formed from a fertilized embryo splitting into 2 separate masses during development. Is this the same as cloning?

9. Learning check
Monozygotic (identical) twins are formed from a fertilized embryo splitting into 2 separate masses during development. Is this the same as cloning? No, when twins form they are splitting a developing organism. Cloning involves placing DNA from another organism into an empty egg.

What is cloning?

11. Learning check
What is cloning? A process involving placing DNA (nucleus) from a body cell of another organism, the nuclear donor, into an empty egg cell.
