In laymens terms, mRNA comes from the nucleus of our cells, the same place DNA is housed. DNA is to big to exit the nucleus but mRNA is a single strand and can exit to be translated and transcribed by ribosomes which in turn produces copies of the proteins read. Please correct me if I’m wrong but I believe this is a simple explanation of how mRNA is used. My question is how can mRNA change your DNA code? mRNA is small enough to exit the nucleus but I am unaware if there is a function of it re-entering. So is it safer to say that mRNA may enable the production of an unnatural protein which then changes a particular function in our bodies instead of saying it changes our DNA? If that’s the case can term GMO still be applied to those who have been vaccinated? Lastly, other than viral load what is the difference between our immune systems reacting naturally with KungFlu and reacting to the vaccine? Obviously the vaccine is not the same as the virus as it has extra ingredients but I am speaking strictly genetically has is it different? Can any docs or scientists help me out with my understanding? Thank you in advance.
