Can't help but wonder if Crisper had moved forward

would we be closer to repairing genetic damage and destroying viruses? Science suspended? most research in this area due to morality concerns. A big hoopla went up after a Chinese scientist edited two twins to make them resistant to HIV. Cells already have technology to cut and edit DNA why not help out?

What is CRISPR?

CRISPR is a molecule that finds a string of DNA code, locks on and makes a precision cut. And because scientists can tune it to target any genetic sequence, they can use it to turn genes off or replace them with new versions.

Short for “clustered regular interspaced short palindromic repeats”, CRISPR evolved in simple, single-celled microbes as a weapon for fighting off viruses. When viruses attack a bacterial cell, for instance, they inject a payload of their own DNA into the cell.

The cell responds by deploying CRISPR, which consists of a strand of ribonucleic acid, or RNA, hooked up to an enzyme called CRISPR associated protein, or Cas.

The RNA is primed to recognise and dock to the virus DNA, neatly encasing it in a pocket of the Cas enzyme. Cas, in turn, makes a cut in the DNA, which disables the virus’ attack.

    At least one test vaccine for Covid 19 is being made using just part of the Covid 19 RNA sequence.  I do not know if Crispr was used, but it certainly seems it could have been perfect for the application.

    I imagine that's how COVID 19 came in to the world.
