Reproductive Cloning

Is used to make a genetic copy of a

living or recently deceased animal.

Making a full living copy requires a

surrogate mother Some animals are easier to clone than

others An Example: Dolly the Sheep

Reproductive Cloning Procedure

o Basic process -- "somatic cell nuclear transfer"

(SCNT)

a) nucleus is removed from donor egg [take adonor egg from animal 1] and placed into another

egg that had its nucleus removed

b) electric current / chemicals are added togenerate cell division

-[a-b] process might be repeated several

times, as it was in Dollys case

c) Once cloned embryo is stable, it transferredinto a uterus of a female host

d) Birth

- Why is Dollys case so amazing? - It proved that a specialized adult cell could be

reprogrammed to create an entire new organism

Reproductive Cloning--the issues

mutations in mitochondrial DNAcould be playing a part in the aging

process. when animals are cloned, most have

problems, diseases or die mysteriously When the genes are moved from cell to

egg, there is always the risk of damage

which can lead to disorders and harm

to the eventually created animal Is extremely expensive, and not very

effective (ex. Dolly was only one

embryo that developed out of 267 that

were implanted)

Therapeutic Cloning

Is the taking of a stem cell from and embryo and producing a certain

kind of cell from it so that it can be used to treat disease or grow

organs.

Example: in 2001, Advanced Cell Technologies sucessfully harvestedstem cells, and inserted into each of them, the nucleus of a skin cell.

The expirament was not very successful though, since the cell that

divided the most only divided 6 times.

Therapeutic Cloning Procedure

the same, "somatic cell transfer" occurs in therapudic cloning as it

does in reproductive stem cells are harvested from embryos to create any type of

human cell

this harvested human cell is then given a new nucleus with newDNA and is shocked so that it reproduces

but instead of putting the newly created egg (from animal 1's

donor cell and animal 2's DNA) into the uterus to develop, it is put

into a tissue culture so that it can multiply
