All About Cloning...
Transcript of All About Cloning...
What is a clone?
A clone is a cell, cell product, or organism that is genetically identical to the unit or individual from which it was derived.
Types of Cloning
The Pros and Cons of Cloning
Just like everything, cloning has its good and bad features. In some ways it brings us to new knowledge. In other ways the results can be unwanted and unreliable.
Is Cloning Ever Natural?
Yes in some cases. Identical twins are produced when a fertilized egg splits, creating two or more embryos that carry identical DNA. This is considered natural cloning. Another example of natural cloning is asexual reproduction, such as the spread of bacteria.
Cloning: Fact or Science Fiction?
Cloning is very real. In fact, when people think cloning they think of Dolly the sheep, the very idol of cloning itself, but Dolly isn't the only cloned organism. Cloning has been around for years!
Reproductive cloning can help parents with no eggs and sperm to have a child of their own.
Endangered animals may be genetically cloned to save their species.
Using frozen cells, extinct animals may be genetically reproduced.
Vital organs can be cloned in order to save many lives.
By genetically cloning diseases and illnesses, scientists may be able to find ways to fight infections and gain resistance or immunity.

Types of Cloning
The three types of cloning include gene cloning, reproductive cloning, and therapeutic cloning.
The cost of cloning is very expensive, and the uncertainty of the process does not make up for it
Clones are susceptible to a short life span, infections, and tumor growth, assuming that the attempt of cloning was successful.
The possibility of cloning humans may result in the clones being devalued and unequal.
There is always the possibility of malpractice in cloning.
The diversity of the genes may decrease, also decreasing our uniqueness and ability to adapt.
Religious views on Human Cloning
Roman Catholic: Opposed
United Methodist Church: Opposed
United Church of Christ: Opposed
Islam: Restricted Views
Judaism: Restricted Views
1952- The first cloned animals, the northern leopard tadpoles, were produced by Robert Briggs and Thomas J. King.
1986- Marsha the mouse was the first mammal to be cloned by Soviet Scientists.
1996- Dolly the sheep was the first animal cloned from adult somatic cells.
2000- Four identical pigs were the products of cloning for the harvest of organs for medical reasons.
2009- Pyrenean Iblex was the first extinct species to be cloned, but the clone only lived for about seven minutes.
With today's technology, it is not too uncommon to clone sheep, cows, or pigs. However, human cloning is disputable territory. Just like any cloning, there are always positive and negative consequences. Just because we can do it, should we?
Is cloning a human playing God?
The Fiction in Cloning
Cloning does not create a carbon copy, only the DNA is identical. Clones and their personalities are affected by their environment.
There is no such thing as instant cloning. The clone will not be the same age as the original organism once it is produced. The embryo of the clone must develop just like the original.
Clones don't always suffer from abnormalities. Some clones live natural lives.
