Does any thing in this life affect the genetical structure permanently? I heard that genetics evolve slowly but could there be a sudden genetic mutation in the human body , if yes is it or not impossible to correct ?

Feel free to share any information that might -even if slightly-help

Thanks , regards.

Well yeah there is the belief that damage to reproductive cells etc can affect genetic structure.

I meant chromosomes in general,

Genetics is commonly attributed to reproduction but I mean the word genetics as it originally means or absolute meaning : from "gens" DNA sequences of a chromosome that being said - do you have any information?

Radiation. Various toxic chemicals. Random errors in cell reproduction.

Well as I said many syndromes develop as a result of some damage to reproductive cells the sperm, egg or in early fetal development. One such syndrome is called smith-magenis syndrome. https://en.wikipedia.org/wiki/Smith%E2%80%93Magenis_syndromeAs for the exact mechanism of how such changes occur I am not 100% sure of I asked here previously.

I haven't heard of those affecting all cells though.

Was that part of the question?

 

Bone marrow transplants can have surprising effects; people have ended with different blood types afterwards.

But is that really changing human chromosomes?? Changing their bone marrow yes. As for whether we can change human chromosomes, human cloning is illegal here.

It is, in the cells affected.

Yeah, but does it affect genetic code of original bone marrow cells in the host or is it just that the implant reproduces and proliferates faster and takes over blood cells production?

I'd also like to add viruses.

True. It is a replacement.

I suppose that is more likely to affect all (or a large proportion) of the cells in the body. (If that was part of the original question. Which it doesn't seem to be.)

Errors in replication and other normal biochemical processes also cause mutations. I.e. it happens all the time. Mutagenic substances just increase the likelihood above the normal baseline.
