Prime editing: DNA tool could correct 89% of genetic defects

A new way of editing the code of life could correct 89% of the errors in DNA that cause disease, say US scientists.

The technology, called prime editing, has been described as a "genetic word processor" able to accurately re-write the genetic code.

It has been used to correct damaging mutations in the lab, including those that cause sickle cell anaemia.

The team at the Broad Institute say it is "very versatile and precise", but stress the research is only starting.



Being able to tweak DNA through gene editing is already transforming scientific research, promising to revolutionise medicine.

This is a very great advance in the world of medicine and can be used to treat diseases as scientists can isolate and reverseĀ genetic errors in experiments on human cells in the laboratory. SinceĀ the vast majority of human genetic diseases are due to the types of mutation that prime editing can correct, the methods will hopefully prove useful in therapies for such diseases. This might however raise ethical issues as people might wonder if changing the genetic makeup is right or moral.

THATs cool, however could this lead to the production of hybrids specimen that can reproduce.
