5.19: Describe the Stages in the Production of Cloned Mammals involving the Introduction of a Diploid Nucleus from a Mature Cell into an Enucleated Egg Cell, Illustrated by Dolly the Sheep

CLONE: Offspring Produced by Asexual Reproduction which are Identical to their Parent Organism

PROCESS OF CLONING MAMMALS:

DOLLY THE SHEEP - 1996

Diagram Showing the Clone of Dolly the Sheep

PROCESS: Diploid Nucleus Extracted from an Udder Cell of a Mature Sheep Enucleated Egg Cell (Nucleus Removed from Egg Cell) Extracted from Another Mature Sheep Diploid Nucleus is Inserted and Fused into Enucleated Egg Cell Egg Cell Given an Electric Shock, Starts Cell Dividing by Mitosis Develops into an Early Embryo and is Implanted into the Uterus of a Surrogate

RESULT: Clone was Identical to the Sheep that the Diploid Nucleus was Taken From (Udder Cell) Dolly the Sheep Died in 2003 without a Scientifically Proven Reason
