Oral
Presentation on Human Cloning
Genetics today is on the
cutting edge of biological science and scientists working in this area are
involved in a wide variety of pursuits that will have profound implications for
our future planet.
PROJECTS
1 . Creation of new biological entities. 2. Curing
diseases. 1 Manufacturing synthetic versions of biological substances. 4
Identifying different genetic codes and what they do. 5. Finding a way to
control genetic information.
A. Genetic information will enable
scientists to produce with or without certain
characteristics:
I . Eliminate hereditary diseases.
Implant
resistance to diseases genetically,
BIOGENETICS
1 . Geneticists
already accomplished many things with grains, plants and certain farm
Animals. 2. Genetic
splicing to create new forms of life for good or ill
A. Great
resonsibility requiring experimentation and development to be conducted
following ethical precepts.
B. Some
people concerned about any and all forms of genetic engineering ‑ the
danger too great ‑ especially the possibility of human cloning.
C. People can be supportive of gene
splicing and recombinant DNA ‑ still oppose
human cloning.
1. They are linked.
2. Constitute a progression in scientific
development.
Recombinant DNA ‑
see photocopy
1 , DNA molecules
derived from different sources that have been artificially spliced
together in vitro to form
hybrid DNA molecules not normally encountered in nature ‑
A, Offers the
opportunity to transcend the limits imposed by nature on hereditary processes.
B. Scientists
can manipulate genes individually by directly modifying the DNA molecules in
which genetic information is encoded.
C. Potential
to transform the genes of all species into a global resource ‑ use to
shape novel life forms obedient to the scientist ‑ rather than dictates
of natural selection. See 'YUCK MAN"
CLONE
1 . Derived from Greek "kion" meaning
twig or slip.
2. Refers to asexual reproduction or
vegetative reproduction.
3. Cloning ‑
production of one or more individual plants or animals (whole or in part) that
are genetically identical to an original plant or animal.
4. Essential
fact of sex in both plants and animals, is that hereditary material from two
individuals are joined to form a new creature.
5. Sex cells
provide diversity ‑ each offspring produced is unique in its combination
of traits.
6. Cloning
does not involve sexual reproduction ‑ clone is not the result of a union
of different material.
7. Procedure
called nuclear transplantation (or cloning), is well established for permitting
asexual reproduction in amphibians ‑frogs, toads, and salamanders.
According to Leon Kass and James Wilson cloning can
be discusses in three familiar
contexts: the technological, the liberal and the
meliorist.
1 . Technological
View‑ an extension of existing techniques for assisting reproduction and
determining the genetic makeup of children. Cloning is to be regarded as a
neutral technique, with no inherent meaning or goodness but subject to multiple
uses, some good, some bad. Morality depends absolutely on the goodness or
badness of the motives and intentions of the cloners.
2. Liberal
or Libertarian Approach ‑ sets cloning in the context of rights,
freedoms, and personal empowerment. A new option for exercising an individual's
rights to reproduce or to have the kind of child that he or she wants ...
cloning enhances our liberation (especially women's liberation) from the
confines of nature ... of chance or the necessity of mating (only egg, nuclei
and uten needed). The only moral restrains ‑ informed consent and the
avoidance of bodily harm. Worries that go beyond violating the will or maiming
the body are dismissed as symbolic ‑ which is to say unreal.
3. Melonst View ‑ embraces
eugenics and valetudinarians. This group see in cloning
a new prospect for
improving human beings minimally by ensuring the perpetuation of
healthy
individuals by avoiding the risks of genetic disease inherent in the lottery of
sex,
and maximally, by
producing optimum babies preserving outstanding genetic material,
and (with the help
of soon‑to‑come techniques for precise genetic engineering)
enhancing inborn
human capacities in all areas. The morality is justified solely by the
excellence of the
end, that is, by the outstanding traits of individuals cloned‑beauty, or
brawn, or brains.
4. Kass and
Wilson View ‑prefers a deeper anthropological, social... ontological
meaning bringing forth a new life. Cloning is a major violation of our natural
right to engender the species and keeping the social aspect of relationships.
They feel cloning is perverse, polluting, and the response of revulsion and
horror by the general public, can only mean it is foul and violating.
Ethics, Cloning and Laws
I
. Cloning raises questions: A. Genetic diversity B. Human identity C.
Exploitation and patenting of human genes D. Antisocial ‑ political
correctness ‑ limits potential E_ President Clinton appointed an 18
member panel ‑The Bioethirs Advisory Commission (NBAC) prohibiting to
attempt research or clinical setting) to create a child through somatic cell
nuclear transfer (human cloning). Five years.
Adult DNA Clonin
1 . Involves
removing DNA from an embryo and replacing it with DNA from a cell removed from
an individual.
2. Embryo is
allowed to develop into a new human whose DNA is identical to that of the
individual. (Dolly the Sheep)
3. If
therapeutic cloning possible ‑ adult DNA cloning will probably be used as
the first step in the procedure.
4.
Embryo's stem cells would later be extracted and encouraged to grow into a
human organ for transplant. A. Heart, liver, pancreas, lungs, skin from a
sample of a person's DNA. B. Has not yet been accomplished in a lab or clinic.
C. Must be encouraged to turn into specific cell types. D. Must be proven
useful in treating patients with diseases, injuries or disorders. E.
Transplanted tissue must develop normally and not be a risk to patient. F. If
possible ‑ perfectly matched replacement organs ‑ no rejection. No
donor. G. In 1998 United States disease advocates and scientific societies sent
a letter to Congress urging them to support federal funding for stem cell
research. H. No waiting. A new organ could be grown as needed. 1. Potential to
cure, treat diseases and disorders.
5. December
1998, a South Korean team of researches claimed without producing scientific
evidence, to have created a human embryo by cloning, using a donor cell from a
thirty year old woman. The researchers halted their experiment after the embryo
divided twice, into a total of four cells, to comply with Korea's national
research ban on more fully developed embryos.
Randolfe Wicker
1 . Founder of Clones Rights Action Center
2. Slogan DOLLY LAMA ‑ OUR NEW
SPIRITUAL LEADER
3. Testified at a NYS Senate hearing
against a proposed bill to ban cloning
4. His
decision to clone himself should not be the government's business or Cardinal
O'Connor's, any more than a woman's decision to have an abortion ... cloning is
highly significant ... it is part of the reproductive rights of every human
being.
5. Appeals
to homosexuals who are fearful of the discovery of a genetic basis for
sexuality ‑ if people are led to abort on a genetic finding, the
homosexual can survive through cloning.
6. His
genotype will triumph, uToo bad Mr. Death... I got another go‑round ...
Let's see what I can do this time out at the box."
IN CONCLUSION
1. Many arguments to the morality of
cloning.
2. Animal rights activists see no
difference between animals and humans.
3. Most of
the population ‑ see benefits to medicine and science found in animal and
plant cloning, cannot accept human cloning.
4. Long term
effects on cloned animals ‑ would not answer challenges by cloned baby.
5. Science fiction ‑ portrays
cloning as creating a carbon copy, an automation.
6. A clone ‑ is really ‑
one of a pair. Twins born at different times.
7. Identical twins are two separate
people. So are clones.
8. Genetic information alone does not
make the person.
9. Take into
account environment and random events that become part of human development.
10.
To ignore time, place, political events, friends, family, neighborhoods and
love, is to say that none of these things had an influence on us. That is those
of us who were conceived by one single sperm that fertilized an egg within our
mother's womb.
11.
End with Aristotle's plainness and efficiency. He offers us logical, sane
advice. To avoid the extremes of behavior, we should choose the 'golden mean' or
middle way, a mode of existence practiced by the virtuous man as a way of
taming the excesses of appetite.
