British Dictionary definitions for cloning clone noun a group of organisms or cells of the same genetic constitution that are descended from a common ancestor by asexual reproduction, as by cuttings, grafting, etc, in plants Also called: Figurative use by Show More clone v. Extension to genetic duplication of animals and human beings is from
There are currently two main functions of cloning: In some countries, both of these types of cloning are used for research. While umbilical cord stem cells are not currently used for either type of cloning, it is very possible that cord blood stem cells will play a vital role in cloning in the future as stem cell research continues to develop.
Cloning is the process of genetic duplication; in cloning, either an entire creature human, animal can be reproduced, or individual cells or genes can be cloned.
Different procedures have distinct regulatory bodies in place so as to monitor cloning. While recently there has been much controversy surrounding cloning, this process has in fact existed for decades.
Plants have been cloned for many years, while a tadpole was the first animal to be cloned in the s.
Sheep, cows and mice have also since been cloned. Cloning can be divided into two main types: Reproductive Cloning The objective of reproductive cloning is to create a genetic duplicate of an organism that either currently exists or that has existed in the past.
This type of cloning can be used for plants and animals, as well as human cloning. In reproductive cloning, a technique also known as Somatic Cell Nuclear Transfer SCNTthe genetic material is removed from a donor egg so as to create an empty egg.
A cell is then removed from the organism that is to be cloned, after which the nucleus of the cell is removed. The cell is then transferred into the empty donor egg and the egg is forced to divide using either chemicals or a mild electrical shock. Reproductive cloning is currently being used in cloning research and could one day help to repopulate endangered species.
Therapeutic Cloning This type of cloning is similar to reproductive cloning; however in this procedure, stem cells are removed from the dividing embryo, which is allowed to die. Cells are then removed from the patient who requires medical treatment.
Chemicals or an electric current are used to cause the egg to divide and the resulting embryonic stem cells are removed from the embryo. These stem cells are then used to treat the patient.Papal Teaching. No one can fail to see the dramatic and distressing consequences of this pragmatism that conceives of truth and justice as malleable qualities that human beings themselves can shape.
Human cloning is the creation of a genetically identical copy (or clone) of a plombier-nemours.com term is generally used to refer to artificial human cloning, which is the reproduction of human cells and plombier-nemours.com does not refer to the natural conception and delivery of identical plombier-nemours.com possibility of human cloning has raised plombier-nemours.com ethical concerns have prompted several nations to pass.
|To Clone or not to Clone: The Ethical Question||Types of Cloning a. When scientists wish to replicate a specific gene to facilitate more thorough study, molecular cloning is implemented in order to generate multiple copies of the DNA fragment of interest.|
Why Human Cloning Is Immoral An article about cloning and how Catholics should deal with this issue. The Governments Make a Move The governments went to work shortly after the cloning of Dolly.
They wanted to take control and make laws before anything drastic could ever happen. Several ethics committees were asked to decide whether scientists should be allowed to try to clone humans.
Conservative position: "Cloning, even so-called therapeutic or experimental cloning, creates a new life without a father, and reduces a mother to the provider of an almost emptied plombier-nemours.comeless, it is a new human life and the determination to destroy it and limit its use to scientific research for therapeutic ends compound further the moral .
"Dangerous, profoundly wrong and has no place in our society " are the words President Obama used to describe human cloning. Has human cloning come far enough along to clone an Egyptian pharaoh from a mummy? Why are there 6 adult stem cells seeking longevity on the International Space Station with Robonaut 2?
