Cloning
CMC 1° Bach
What is Cloning?

Reproductive cloning is a technology used to
generate an animal that has the same nuclear
DNA as another currently or previously existing
animal.

Dolly was a sheep created by reproductive
cloning technology.

Dolly or any other animal created using
nuclear transfer technology is not truly an
identical clone of the donor animal. Only the
clone's chromosomal or nuclear DNA is the
same as the donor.

Stem Cell Research

What are Stem Cells?

Stem cells are cells that develop into
different cell types in the body during
growth. Different parts of your body are
made up of different kinds of cells.

Stem cells are not specific to one area in
the body and can turn into skin, bone,
blood or brain cells.
Stem Cells

Stem Cells Are Special

Stem cells are different than other cells in
many ways. For one, they can renew
themselves by dividing into more stem cells
more than once.

Scientific Research

Scientists are researching stem cells and
have discovered many interesting things
about them.

Some scientists believe stem cells can cure
diseases, cause hair to grow for bald
people, and can be used to grow organs
such as livers and kidneys.
Stem Cell Harvesting

Therapeutic cloning produces stem cells
which can develop into different types of body
cell, making them ideal for research into
treatment of disease.

But this technology involves the creation and
destruction of embryos, which is ethically
controversial. The stem cells created also run
the risk of being rejected by the body.

The new technology, nuclear
reprogramming, creates stem-like cells from
the patient's own cells, avoiding both these
problems.

Types of Stem Cells:

There are two types of stem cells: adult and
embryonic stem cells.

Adult stem cells turn into many different
cells of the same basic kind.

Embryonic stem cells can turn into
almost all of the body's cell types with a
few exceptions.
Stem Cells

Research:

Stem cell research has much support from
the American people but has not received as
much from the United States government.

As a result, many scientists research stem
cells in other countries that support their
research projects
The Stem Cell Debate

Cloning:

Because of the stem cell's ability to transform into
any other type of cell, much of stem cell research is
directed towards human cloning.

There are two types of human cloning: reproductive
and therapeutic.
 Reproductive cloning is essentially cloning to
produce children, while therapeutic cloning is
used only for scientific research.
 While cloning to produce children is not yet
possible, stem cell researchers hope that one
day it will become a feasible option.
Human Cloning: Your
Opinion

Answer the following questions about
human cloning independently.
1. Do you agree that human
cloning should be legalized?
2. Do you think it is unethical
to clone a human?
3. If you were dying and
needed a donor organ to
live, would you clone yourself
to create the organ?
4. Do you think a human
clone would live a normal
life?
5. Should scientists be
allowed to use human
cloning to create children for
infertile couples?
6. Do you agree that human
cloning is above human
power and should be illegal?
7. Are you for or against
human cloning?
What do you think???

Cloning the First Human- BBC Horizon
Benefits of Human Cloning:

Better genetic traits can be produced

Better medicines

Recreate endangered or extinct animals

The possibility to recreate life

Cloning of human organs
Benefits of Human Cloning:

Ability to rejuvenate the human body (make
our organs younger)

Reduction in the speed of aging

Problems with Famine (meat could be
produced at large quantities by cloning
animals)

Price and Availability of Food
Why Should We Fear Human
Cloning?

Two identical beings will be living (more
identical than twins)

Mental Cloning (people with the same skills,
history, memory and personality traits)

Fear of having thousands of people identical
to each other in the world

No diversity of thought, reasoning, or
opinion
Group Debate:

Divide yourself into two groups:

Group 1: For Human Cloning

Group 2: Against Human Cloning
Group Debate:

Each group must create a short argument
to defend their stance regarding human
cloning.
