extra copies of genes

[effects]

Can a mutation that contributes to aging occur on any & even every copy and/or extra copy of a gene chromosome etc, no matter how many there are?

 

Also disregarding the theoretical use of cell, organ, and tissue transplants, and gene therapy to replace mutated genes, to solve etc the issue of aging from mutations that contribute to aging there are no ways (other than the potential ways listed in this post) to completely solve etc the issue of aging from mutations that contribe to aging with our current technology etc correct?

 

only answer this post if you are answering as accurately as possible whenever you answer..thanks..I really appreciate the help

If you had backup copies of the various genes you need, then mutations are less likely to do any noticeable damage. However, some genes will overproduce proteins if extra copies are expressed, so you can't just go doubling the entire chromosome and expect there to not be bad side effects.
