Researchers Clone Calf From Cloned BullA clone of a cloned prized bull thrives today on a Japanese farm, living proof that "serial cloning" can successfully create life beyond mice.
The second generation cloning that created the black bull named Kamitakafuku took place in 2000, but wasn't announced until Sunday because researchers wanted to ensure the bull matured and was healthy. The only other mammal known to have been cloned from a clone are mice.
( Interested? )To clone, researchers replace the genetic material in an egg with the DNA from the animal to be cloned.
With a little jolt of electricity and other laboratory maneuvers, the egg is tricked into believing it's fertilized and grows into an exact genetic copy of the donor.While cloning researchers are becoming much more proficient with their craft, many problems still persist.
It can still take hundreds of cloned eggs to yield a single offspring and many are born obese and with other health problems.
Researchers attempting to clone clones beyond the mouse have failed until Yang published his work.
Yang hopes his recloning work will help him uncover key genes responsible for the reprogramming errors.

Clearly, the music is starting to mellow me. This may not be good--I've moved books all day in heat. I have a massage to give and a dance class yet!
