experiments such as cloning have been successful‚ but they bring along with them some very negative results‚ for example‚ in some early experiments in animal cloning some potential dangers had been encountered‚ cloned cows developed faulty immune systems‚ other projects which created cloned mice‚ grew obese‚ and in most studies‚ cloned animals seemed to grow old faster and die younger than the usual members of the species.

When a properly functioning immune system detects an unknown substance‚ it responds to this threat by producing proteins called antibodies against the invaders. The antibodies
