How do animals get cloned?

Question

i dont get it.... how can they clone a dog or other animal?????

Answer 1

i might be wrong, but what i know is that to clone any animal,you get any of its diploid cells,and its ovum, you then remove all the contents from its ovum so that you only remain with the ovum shell. you then insert the diploid cell into the ovum shell and allow this to develop in a suitable culture.

Answer 2

Clones are the exact genetic copy of someone, or something. So you need the same set of genetic material from the cells. If you know who is Dolly, Dolly was a clone of her mother. The simplest cloning involves the removal of the nucleus from the cell from any part of the body. Then the cell is put in an ovum cell which has all its contents removed and then simply put in a female's womb until gestation. This is a complicated case for humans where even more complicated processes are involved.

Answer 3

There are two ways an animal may be cloned: one natural, one unnatural.

The natural way is when, in the womb, the blastocyst starts developing as two separate bodies, thus creating identical twins, which are technically clones.

But, I'm assuming that you meant how can it be done like with Dolly the sheep. First, you take an egg cell from that animal, and remove the material. Then, you inject the DNA from the animal into that egg from one of the somatic cells (any cell that is NOT a sperm or an egg). After that, you send a series of electrical currents through the egg in order to stimulate it to start dividing. From there, a clone is starting to form. They place the embryo into the uterus of that animal, where it will grow until it comes to term.

It is very hard to do this procedure; removing the nucleus and replacing it is very traumatic for the egg; many are destroyed in the process. Also, implantation for clones also is difficult to take; it took more than 200 attempts before Dolly came into existance.

Answer 4

to produce the clone of an animal,a sample of its DNA must be used..since each body cell contains a complete DNA genome this is easily obtained....this DNA has to be introduced into the ovum (egg) of another animal of the same species after the ovum's original DNA is extracted..the egg is then inserted into a surrogate animal's womb and the pregnancy proceeds as normal...although every body cell contains a complete genome,it will normally activate only those genes necessary for its own body part..for eg..kidney,brain or bone....the other genes are not needed and are not "switched on"...however if the cell is starved of nutrients,developement can be stopped at early stage,at which point all the genes can be operative...the ovum into which the DNA is inserted will then behave as if the DNA were its own.....in july 1996,Dolly,a perfect clone of an adult sheep, was born...of 277 cells fused with ova,as in the sequence left,she was the only lamb to be born......

Answer 5

Simply put,  in animals, a cell's nucleus  which has all of its genetic information ( chromosomes or genes) , is removed;  new genes from another animal is added to the original cell. the end product is an animal that looks exactly like the     donor of new gene . Most commonly, the chosen cell is an egg, but other cells can be used, also.

Otherwise substitute  all of the genes from an animal cells  with another( usually same species).  

Cloning has been performed successfully in bacteria as well.

Answer 6

The process is called "Somatic Cell Nuclear Transfer" (SCNT), and is performed by taking a fertilised egg, and removing its nucleus. You then take a normal body ("somatic") cell from the individual to be cloned, and extract its nucleus. You then transplant that nucleus into the enucleated egg, and implant that into the uterus of a female.

Since all the DNA comes from one donor, it is a genetically identical copy of that individual - it is their clone.
