Dolly the sheep - the first cloned mammal

1. Dolly the sheep - the first cloned mammal

2. The Birth Of Dolly

Dolly born 5 July 1996
Roslin Institute, the
Scottish, and six months
later in February 1997, this
event shocked the whole
world - Dolly was cloned
from breast cells 6-year-old
adult sheep by transferring
the nucleus of the cell.

3. the history of cloning

Reports of cloning frogs
appeared in the fifties of the
last century, when by
transplanting the nucleus of
the cell tadpole in the calf
was obtained by a new
tadpole, that is
fundamentally the
possibility of cloning cells
has already been proven.

5. The Uniqueness Of Dolly

Dolly is the only mammal that doesn't have a
father, but has three mothers. The sheep that gave
its genetic material, the sheep that took the egg,
and the sheep that received the famous lamb.

6. The creators of Dolly the sheep

The experiment was staged by Ian Wilmuth and Kate Campbell at the Roslyn
Institute in Scotland near Edinburgh in 1996.

Dolly was the only survivor of 244, but now this
procedure is increasingly used in cloning goats,
mice and calves (survives about 3%).

8. Dolly's Fate

Dolly became the most
famous sheep in the history
of science. She lived 6.5
years as an ordinary sheep
and left behind 6 lambs.
Dolly was put to sleep in
2003 due to discovered
diseases and her stuffed
animal was exhibited at the
Royal Museum of Scotland.

The prospects of cloning :
1. The use of stem cells for the treatment of
diseases characterized by significant tissue
damage (strokes, paralysis, diabetes, heart
attack, the consequences of injuries and burns).
2. The cultivation of stem cells of organs that
do not cause rejection.
3. The attainment of children of
infertile families.
4. The creation of highly productive
herds of farm animals.
5. Restoration of extinct species and
preservation of rare ones.
