Vaccines made from mRNA? Could they mess up with our DNA? First, what is mRNA
Posted by: adonis49 on: December 19, 2020
| Vaccines based on genetic material may give you pause. But mRNA vaccines, which have been in the works for nearly three decades, never touch our DNA. As a result they can’t interfere with human genes. Instead, they just borrow some of our cellular tools before harmlessly breaking down in a matter of hours. Specifically, mRNA vaccines for Covid-19 take advantage of our cells’ protein-making factories, called ribosomes. Normally, our ribosomes create proteins based on recipes from our own DNA, which is locked up inside the nucleus, a protective, membrane-covered bubble within our cells. The vaccine shot delivers a microscopic, fatty package into our cells, carrying a recipe—the mRNA sequence—for a protein that mimics the SARS-CoV-2 virus. When that mRNA meets up with our ribosomes, our ribosome chefs interpret this new mRNA as if it were a recipe generated from our own DNA, but the DNA inside the cell’s nucleus remains untouched. Question: And if the cell membrane gets punctured, weak and unhealthy… and the mRNA sequence seep through and alter the DNA? What kind of a new human species we end up with? |
