DNA Technology : Cloning Prepare your notebook for Cornell Notes

Click & Clone Lab QUICKWRITE: In your on words explain the process of the click and clone lab demonstration. What were the steps? What was the purpose? What was created? How?

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.

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.

Cloning Steps

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?

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

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.

Learning check What is cloning?

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.
