What is Cloning?

Cloning

Intro to cloningCloning is the process in which two organisms are created with the exact same genetic makeup. This happens naturally in twins, and has also been demonstrated through several lab experiments

Why Clone?

Somatic Cell Nuclear transfer is another way of cloning. Insteadof using a sperm and egg cell, a somatic cell is used with an egg, whichis any other cell than a sperm or egg cell. The DNA from the nucleus is taken from the somatic cell and is placed in an egg. the egg is then placed in a mother to developsomatic cell and is placed i

The difference between cloning genes and organisms is very apparent. Cloning a gene simply involves inserting a gene into bacteria and allowing them to reproduce, thus allowing offspring to produce more of the genetic material.Cloning an organism, however, involves taking all of the nuclear DNA and completely replicating it, which can take thousands of tries and is much more complex.

Cloning animal models for disease speeds upthe process of breeding animals with a certain gene.Rather than waiting several generations for the geneto appear in the animal's genetic makeup, it can be directly inserted in the cloning process.Stem cells can also be created from the process of cloning.These cells repair and reconstruct tissues in our bodies, andare person specific, making transplants of these cells verydifficult. However with cloning, you can make direct copies of your own cells, making the process much easierCloning can also be used in the field of agriculture, as farmersare already starting programs to clone livestock. The Geneticsof their prized and superior cows can be directly copied and therefore the wanted genes will appear in the next generation.

There are several myths about the processof cloning and how it works. Some even thinkthat the generation of an identical clone isinstantaneous, but the reality is the offspringwill have a normal development time. Another myth associated with cloning is that offspring are carbon copiesof the parent, and this simply isn't true. Enviornmentalfactors still play a large role in the development of the organism.

Cloning by SCNT is far different than normalmeans of fertilization. Instead of two sex cellsjoining(one sperm, one egg), a somatic cell, whichis anything other than a sex cell, has it's total nuclearDNA extracted and inserted into an egg. Rather thanexperiencing genetic variation, the offspring's genesare identical

Artificial Embryo twinning is a way of creating clones. The process involves taking a fertilized egg cell at an early age and splitting it in a petri dish. The cells then divide for some time, and are then placed into a mother to finish development.

The cloning timeline began somewhere around 1885, where an embryo was twinned on a sea Urchin. In 1952 the first successful nuclear transfer was done on a frog and later in 1984, a sheep was cloned. Later in 1996, dolly the sheep was cloned, and it was the first successful Somatic cell nuclear transfer.
