How do people clone animals and where is it legal?

Question

Ok I know they cloned a dog but how can they do that?

Answer 1

people clone animals with the help of the tissues in the womb of the same animal, they ll provide the same atmospehre as in of a womb, the main idea of cloning is t improve the abilites of the animals...

Answer 2

As far as I know, there are no legal limitations on farm animal cloning, just regulatory requirements.

See: FARM ANIMLA CLONING: THE CURRENT LEGISLATIVE FRAMEWORK

Animal cloning isn't really all that difficult in practice, just very, very intricate in details.  Current techniques involve the extraction of differentiated (adult cell) somatic cell from the animal to be cloned, culture this cell in the lab until significant population size, then starve the cell culture until cells move out of the normal cell cycle and into the G0 phase, kind of a holding phase.  Once in the G0 phase, the whole cell is microinjected (or fused) with an enucleated egg cell (one that has had its own nuclei removed). This egg cell is then "activated" with a short burst of electrical energy, cultured in vitro for about 4 days and then implanted in the womb (uterus) of a surrogate carrier to be brought to full term.  Now, that is the simplfied version.  If one was to be more efficient in animal cloning, they'd would modify the above proceedure slightly by doing two things: 1. add a component of cancer cell cytoplasm to the newly formed cloned egg; 2., they would insert the cloned egg into the surrogate's fallopian tubes instead of waiting 4 or 5 days of development for injecting it directly into the uterus.  Two steps that make a difference; all the difference in the world.

Cloning technique isn't the limiting factory so much as the actual cost of carrying out the procedure.
