“the problem with telomeres” you have to be a LOT more specific.
telomeres are good, useful things that make up for the fact that the cell is really bad at making copies. some cells can make copies without losing there telomeres, we call those “cancer” (they also refuse to kill themselves when the other cells ask them to, greedy bastards)
but i don’t know what problem you are talking about, far as i know there is no problem relating to telomeres and cloning.
