(No Transcript)
3
Pros
  • Cure human diseases
  • Using animal organs
  • Create animals that are disease resistant
  • More consistent food products
  • Save endangered species

4
Cons
  • Public perception
  • Use technology to clone humans
  • Expensive
  • Not efficient
  • Cloned products cannot be marketed

5
Cloning
Definition The process of making
identical genomic copies of an original
animal.
Encyclopedia Britannica An individual organism
that was grown from a single body cell of its
parent and that is genetically identical to it.
6
Brief History of Cloning
  • 1902 Walter Sutton proves chromosomes hold
    genetic information.
  • 1902 German scientist Hans Spemann divides a
    salamander embryo.
  • Spemann proposes a fantastical experiment

7
Brief History of Cloning
  • 1952 Briggs and King clone tadpoles.
  • 1953 Watson and Crick find the structure of DNA.
  • 1962 John Gurdon clones frogs from
    differentiated cells.
  • 1963 J.B.S. Haldane coins the term clone.

8
Brief History of Cloning
  • 1977 Karl Illmensee creates mice with only one
    parent,
  • 1984 Twinning- create genetic copies from
    embryonic cells.
  • 1996 First animal cloned from adult cells is
    born.

9
The Cloning Process
  • 1978 Splitting embryos
  • 1986 Embryo Cloning
  • 1994 Embryonic cell line cloning
  • 1996 Adult or Somatic cell cloning

10
Creating Dolly
11
Stage 1
Cell collected from a sheeps udder.
12
Stage 2
Nucleus is removed from unfertilized egg of
second sheep.
13
Stage 3
Udder cell is inserted into egg with no nucleus.
14
Stage 4
Insertion is successful.
15
Stage 5
Electrical charge is supplied.
16
Stage 6
Cells begin to divide.
17
Stages 7 8

Cloning Facts
  • Plant cloning has been around for thousands of
    years
  • Farm animal cloning has been around for over 20
    years
  • Cloning is a form of asexual reproduction
  • Clones are not exact copies
  • Cloned animals are safe to raise and eat

19
Cloning Fallacies
  • Genetic make-up is altered
  • Mutants are created
  • Clones are unhealthy
  • Will eventually lead to cloning humans
  • Possible to recreate people such as Hitler

20
House Bill 2505Human Cloning Prohibition Act
  • Prohibition on human cloning
  • Criminal Penalty Up to 10 years imprisonment
  • Civil penalty Minimum 1 million dollar fine

21
Final Thoughts
  • Cloning has been around for a long time
  • Cloned products are safe
  • Useful in medical and pharmacological fields
  • Will not replace traditional animal agriculture
  • Need to better educate public
  • Close regulation
