risks and Benefits? Risks: Benefits: What is the What animals have been cloned? When? What is cloning? Are there different types of cloning? A clone is an identical copy of a plant or animal, produced from the genetic material of a single organism. DNA Cloning Reproductive Cloning Therapeutic Cloning DNA Cloning Reproductive Cloning Technology that can be used to make multiple animals or human beings. a process known as SCNT, which stands for "somatic cell nuclear transfer." In this process, genetic material is transferred from the nucleus of a donor adult cell to an egg whole nucleus has been removed. this reconstructed egg must be treated with chemicals or electric current in order to stimulate cell division. Transgenic falls into this type of cloning. Therapeutic Cloning Another name for therapeutic cloning is "embryo cloning." This process isn't meant to create or clone humans, but to grow stem cells and study them to treat disease and study human development. Stem cells can be used to generate any cell in a human's body and extracted from the egg after division of 120 hours. Embryology is this type of cloning http://www.freewebs.com/mikegrasis/Reproductive%20Cloning.htm http://www.nap.edu/openbook.php?record_id=10285&page=7 http://avonapbio.pbworks.com/w/page/9429274/Ch%2020 Works Cited: http://www.freewebs.com/mikegrasis/Reproductive%20Cloning.htm http://www.nap.edu/openbook.php?record_id=10285&page=7 http://avonapbio.pbworks.com/w/page/9429274/Ch%2020 http://www.ornl.gov/sci/techresources/Human_Genome/elsi/cloning.shtml 1. 2. 3. 4. https://bsp.med.harvard.edu/ 5. http://www.sciencemuseum.org.uk/antenna/dolly/122.asp 6. Dolly, a sheep, was cloned in 1996.
A cloned baby bull gaur, Noah, was the first endangered animal to be cloned. This experiment opened up the scientist's eyes and they realized they could clone other endangered species. 1880s: Wilhem Roux confirmed the theory August Weismam proposed; "the genetic information of a cell would diminish with each cell division." history of cloning? 1901: An experiment
Hans Spemann
had done shows
that early embryo cells can develop into a new organism because they retain the genetic information necessary. 1902: A hypothesis by Walter Sutton stated that "chromosomes hold the genetic information in the nucleus." 1914: The first successful nuclear transfer experiments were completed by Spemann. 80 90 00 10 20 60 70 80 90 00 1964: F.E. Steward of Cornell University proved that cloning differentiated cells was possible by conducting an experiment of growing a complete carrot plant from a fully differentiated carrot root cell. 1972: The first recombinant DNA molecules were created by a scientist at Stanford University. Three mice were claimed to be cloned by Karl Illmensee. 1979: 1990: "The Human Genome Project began. This international collaborative effort attempted to sequence the entire genetic makeup of humans, consisting of more than three billion nucleotides." https://bsp.med.harvard.edu/ 2001: Noah was born.

abnormal gene expression patterns.

list. For Cloning: Against Cloning: Support of scientific research.
Recovery of lost loved ones.
Infertility: cloning a fertile copy of themselves.
Eugenics: making a superhuman race.
Creation of spare body parts.
Reproduction of their own qualities. Playing God.
Determining gender.
Sexual orientation.
Embryos at risk.
Embryos killed.
Human rights. Our Opinion: We are both for and against cloning. What we mean by that is, we think it's okay to clone animals, but not humans. Why do we think this?
Well, let's take you and your pet for example. You get really close with your pet over the years and they become your best friend. When it becomes their time, you could possibly go into depression. You can then turn to cloning. Even if it's not the exact animal, it is very close.
When you think about cloning a human being, it just doesn't sound right. It disrespects nature along with God. When cloning people, everyone is no longer different. Everyone is unique in their own way and by cloning, it would destroy this statement. Also, cloning humans could lead to slavery. In 50 years, do you want to live in a world that revolves around having slaves? Quiz! 1. 2. 3. 4. 5. What are two risks of cloning? What type of animal was first cloned and what was his/her name? Are we for or against cloning? What is The Human Genome Project? TRUE or FALSE: Illmensee claimed to have cloned two mice. An international project to map the entire genetic material of a human being. high failure rate.

abnormal gene expression patterns.
telomeric differences A sheep named Dolly. FALSE:
He cloned
three mice We are both; we are for animal cloning and against human cloning. DNA Cloning, also called "gene cloning", is when DNA is transferred from 1 organism to a self-replicating genetic element such as bacterial plasmid. Then the inserted DNA spreads in a foreign host cell creating the clone. This is classified as genetic engineering. C L O N I N G ! By: Ally Johnson
