sooroor Posted February 4, 2016 Share Posted February 4, 2016 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. Link to comment Share on other sites More sharing options...
fiveworlds Posted February 4, 2016 Share Posted February 4, 2016 Well yeah there is the belief that damage to reproductive cells etc can affect genetic structure. Link to comment Share on other sites More sharing options...
sooroor Posted February 4, 2016 Author Share Posted February 4, 2016 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?

Strange Posted February 4, 2016 Share Posted February 4, 2016 Does any thing in this life affect the genetical structure permanently? Radiation. Various toxic chemicals. Random errors in cell reproduction. 1 Link to comment Share on other sites More sharing options...
fiveworlds Posted February 4, 2016 Share Posted February 4, 2016 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. Radiation. Various toxic chemicals I haven't heard of those affecting all cells though. Link to comment Share on other sites More sharing options...
Strange Posted February 4, 2016 Share Posted February 4, 2016 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. Link to comment Share on other sites More sharing options...
fiveworlds Posted February 4, 2016 Share Posted February 4, 2016 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.

Strange Posted February 5, 2016 Share Posted February 5, 2016 But is that really changing human chromosomes?? It is, in the cells affected. Link to comment Share on other sites More sharing options...
pavelcherepan Posted February 5, 2016 Share Posted February 5, 2016 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? Radiation. Various toxic chemicals. Random errors in cell reproduction. I'd also like to add viruses. Link to comment Share on other sites More sharing options...
Strange Posted February 5, 2016 Share Posted February 5, 2016 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? True. It is a replacement. I'd also like to add viruses. 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.) Link to comment Share on other sites More sharing options...
CharonY Posted February 5, 2016 Share Posted February 5, 2016 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. 1 Link to comment Share on other sites More sharing options...
