Cloning describes the processes used to create an exact genetic replica of another cell, tissue or organism . The copied material, which has the same genetic makeup as the original, is referred to as a clone.
What is the description of a clone?
Cloning describes the processes used to create an exact genetic replica of another cell, tissue or organism . The copied material, which has the same genetic makeup as the original, is referred to as a clone. The most famous clone was a Scottish sheep named Dolly.
What is the clone in genetics?
Listen to pronunciation. (klone) An identical copy of a DNA sequence or entire gene ; one or more cells derived from and identical to a single ancestor cell OR to isolate a gene or specific sequence of DNA.
What is an example of a clone?
The definition of a clone is a copy of something, or an organism or cell that has the same genetic makeup as another. When someone makes a knock-off copy of an iPhone, this is an example of an iPhone clone. When scientists make a genetic copy of a sheep , this is an example of a clone.
What are the risks of cloning?
Researchers have observed some adverse health effects in sheep and other mammals that have been cloned. These include an increase in birth size and a variety of defects in vital organs , such as the liver, brain and heart. Other consequences include premature aging and problems with the immune system.
What was the first animal to be cloned?
Dolly the Sheep was announced to the word with a paper published in 1997, in the journal Nature, succinctly titled “Viable offspring derived from fetal and adult mammalian cells”.
What are 2 examples of cloning?
- vegetative reproduction in plants, e.g. water hyacinth producing multiple copies of genetically identical plants through apomixis.
- binary fission in bacteria.
- parthenogenesis in certain animals.
How do you clone yourself?
So, it’s currently theoretically possible to clone yourself , although no one has done it or tried it yet. This clone would grow up to look exactly like you, be your genetic brother or sister, and have the same genetic predispositions as you do.
What are the pros and cons of cloning?
- Pro: Reproductive Cloning. Reproductive cloning has a number of pros. ...
- Pro: Organ Replacement. ...
- Pro: Genetic Research. ...
- Pro: Obtaining Desired Traits in Organisms. ...
- Pro: Recovery from Traumatic Injury. ...

- Con: Increased Malpractice. ...
- Con: Lack of Diversity.
Is cloning unethical?
Human reproductive cloning remains universally condemned, primarily for the psychological, social, and physiological risks associated with cloning. Because the risks associated with reproductive cloning in humans introduce a very high likelihood of loss of life, the process is considered unethical . ...
Why Should cloning be banned?
In addition to the above ethical considerations, research cloning should be forbidden because it increases the likelihood of reproductive cloning . Preventing the implantation and subsequent birth of cloned embryos once they are available in the laboratory will prove to be impossible.
What are the disadvantages of human cloning?
- Cloning humans might always be an imperfect science. ...
- Cloning humans would be a technology initially priced only for the wealthy. ...
- Cloning humans might create a rapidly aging population. ...
- Cloning humans could alter our perceptions of individuality.
Is it legal to clone animals?
There are currently 8 states (Arizona, Arkansas, Indiana, Michigan, North Dakota, Oklahoma, South Dakota, Virginia) that prohibit cloning for any purpose. ... There are 10 States ( California, Connecticut, Illinois, Iowa, Maryland, Massachusetts, Missouri, Montana, New Jersey, and Rhode Island ) with “clone and kill” laws.
Is human cloning legal?
Of the nine states that currently have human cloning legislation in place, four states — Arkansas, Iowa, Michigan, and North Dakota — prohibit both reproductive and therapeutic cloning, while three states — California, Louisiana, and Rhode Island — ban reproductive cloning but permit therapeutic cloning .
Why is Dolly the sheep called Dolly?
Dolly was cloned from a cell taken from the mammary gland of a six-year-old Finn Dorset sheep and an egg cell taken from a Scottish Blackface sheep. ... Because Dolly’s DNA came from a mammary gland cell, she was named after the country singer Dolly Parton .
What are the 3 types of cloning?
- Gene cloning, which creates copies of genes or segments of DNA.
- Reproductive cloning, which creates copies of whole animals.
- Therapeutic cloning, which creates embryonic stem cells.
