Answer #1

Basically when cells divide, they can only do this a certain amount of ‘divisions’. I am not sure how exactly it works but I’m pretty sure it is in the nucleus (isn’t everything? lol). The reason Dolly the clones sheep died at half a sheeps expected age was because the cells that had been cloned reached their hayflick limit for the entire body only after about 6 years, because the sheep it was cloned from was already 6 or 7.
