The major challenge in using adult DNA in the cloning process is reprogramming it to function like the DNA of an egg. Adult cells have already specialized into their specific roles, and thus their DNA is programmed to express certain genes and not others. In order to create a clone, the DNA must be reprogrammed to function like the DNA of an egg, which is capable of becoming any type of cell. This process is difficult and often results in abnormalities in the resulting clone.
