(2) Both are very similar, yet have their differences also. But, more importantly, lets talk about their functions.
DNA replicates and stores genetic information. It is a blueprint for all genetic information contained within an organism. RNA converts the genetic information contained within DNA to a format used to build proteins, and then moves it to ribosomal protein factories.
The mRNA vaccine is a synthetic "messenger" RNA strand, that converts genetic information within DNA.
Now, they've told you that they do this to produce proteins to in order to strengthen the immune system to fight the Covid virus, but if you really look at the bigger picture here, it might leave you quite numb to understand the potential reality of the situation.
If you have had the vaccine, rest assured that your DNA is now changing. Do you have any idea of the implications of that? Your genetic makeup is mutating.
You are being put under extreme pressure to take a substance that changes you
