How could cloning be put in use?
● There are many ways to put cloning into use
– Medical purposes– Reproducing endangered animal
species– To help infertile people to have
children

Medical Purposes
● Scientists learn about how human diseases by studying from animals
● Cloning will create genetically identical animals so that scientists can study them
– That will help make the research more accurate, considering all the animals would be genetically the same

Cloning endangered Animals
● Many animals are endangered, and if you can
clone these animals it can prevent extinction
Noah was a cloned Gaur. The Guar was going extinct. Unfortunately, Noah died 2 days after his birth due to a common bacterial infection

Helps infertile people have children
● Cloning could be used to help couples who can't have children
– They could clone a child, so that they can have their own

Side Effects/Disadvantages
● Builds a superficial society– People may start trying to make their
children perfect—make them smarter, stronger, more beautiful
– Eliminates differences● Each person is unique in their own way,
if you're cloning people not everyone will be different

● Unreliability – The mutations or complications that
could come from cloning can't be undoable . You can't put a human's life in jeopardy

How expensive is cloning?● Cloning generally is very expensive. The price
varies from what organism you are using, because the cost of the eggs are different.
● A human egg donor is paid $3000 to $5000 where as you can get 4000 mouse oocytes for $2000
● If you did the same with the humans , it would cost approximately 2 million
● It costed about $750,000 dollars to make Dolly the sheep (not including the years of research)

Process of Cloning
● The most common method is 'stomatic cell nuclear transfer' also known as 'nuclear transfer'
● A stomatic cell is a cell that isn't a sperm or egg that has the complete DNA of the organism it came from
● To clone, you need a stomatic cell and an egg cell
![Page 10: Cloning](https://reader035.fdocuments.us/reader035/viewer/2022070316/555e7311d8b42a41328b468d/html5/thumbnails/10.jpg)
● First, you have to isolate the stomatic cell and the egg cell from both donors
● You then remove and discard the nucleus, because the nucleus contains the egg donor's genes
● Then you transfer the stomatic cell into the egg cell, and the egg will have the egg cell donor's DNA
● After that is completed, you have to stimulate cell division
– Use stimulating liquids to allow the cell to divide with regular meiosis

● Lastly, you need to implant the embryo into a surrogate mother

Cloning Controversies
● In 2002, George Bush first tried to ban all human cloning
● Many people believe that human cloning is morally wrong, especially when it comes to human cloning
● Some people may believe that cloning is exploiting one person for another.Every human being is supposed to be unique and completely copying another would oppose that
● Others believe that cloning can help medical advancements
