Cloning is also problematic given our limited knowledge and crude techniques..
The clones are not exactly perfect copies...
I saw where commercial companies now will produce a clone of a beloved pet... I would not do this, the clone looks the same but it’s not so I’d rather just remember Fido and leave it at that.
Every time a cell divides the cells timer loses a set of telomeres from the gene sequence. When they’re gone the cell stops dividing. What happens to the clones which start out with a depleted clock?
