Is it true that identical twins are truly identical in terms of their nuclear DNA and mitochondrial DNA . . .?

. . . but a clone only has the same nuclear DNA. Also, if a person used their own egg and cloned themselves by inserting their own nuclear DNA would the clone be an exact copy?Is it true that identical twins are truly identical in terms of their nuclear DNA and mitochondrial DNA . . .?
It is highly probable that identical twins have exactly the same nuclear DNA and mitochondrial DNA, but it is not guaranteed. Transcription errors happen.





';but a clone only has the same nuclear DNA';





Cloning is not a natural process. To the best of my knowledge, when people speak of cloning, they are talking about replacing only the nuclear DNA, but if there were a compelling reason to replace the mitochodria as well, probably somebody could figure out a way to do that.





';if a person used their own egg...';





Um, I think that would be closer to the truth if you said, ';if a woman used her own egg...';Is it true that identical twins are truly identical in terms of their nuclear DNA and mitochondrial DNA . . .?
Well they can't be exactly alike like one might be stronger,smarter,taller,or even more healthy.
