History of the Science of Creating Life How

History of the Science of Creating Life How long ago do you think was the first time a scientist “created” life?

1885 – Very first scientific “creation of life” Sea Urchin cloning

1885 – Very first scientific “creation of life” Sea Urchin cloning 1902 – Salamander cloned (with baby hair) “Twinning”

1885 – Very first scientific “creation of life” Sea Urchin cloning 1902 – Salamander cloned (with baby hair) “Twinning” 1928 – First Clone via Nuclear Transfer (another salamander)

Spemann's 1928 Nuclear Transfer STEP 1: Spemann tied a single strand of hair into a noose and pinched off a region of cytoplasm from a single celled salamander embryo. STEP 2: The part of the cell containing the nucleus grew normally, and developed into a multi-celled embryo. The region of pinched cytoplasm remained unchanged. STEP 3: Spemann loosened the noose, and allowed a nucleus from one of the embryo cells to enter the isolated region of cytoplasm. STEP 4: Spemann then severed the multi-celled embryo from the cytoplasm. The region of cytoplasm, which now contained a nucleus, began to develop into a normal embryo.

1953 – Structure of DNA was discovered

1953 – Structure of DNA was discovered 1968 - Molecular biologist Har Gobind Khorana wins Nobel Prize for describing the Genetic code of DNA. This aids in new testing in cloning and engineering for plants and animals.

1953 – Structure of DNA was discovered 1968 - The Genetic code of DNA is described 1975 – Scientists claim to have cloned a rabbit via Nuclear Transfer 1986 – A sheep cloned via Nuclear Transfer 1987 – A cow cloned via Nuclear Transfer 1996!

Hello Dolly!!!

1996 – Dolly was born! Somatic Cell Transfer http: //www. dnatube. com/video/563/Somatic-Cell. Nuclear-Transfer-Animation

For the first time in history, a life is created WITHOUT the need for… a man.

On back side of timeline… • Reflect on this event… • What does it mean? ? ? • Where are we going? ? ?
