[http://www.samuelcyprial.com.ng/2017/09/chinese-researchers-has-correct-genetic.html]A team at Sun Yat-sen University used a technique called base editing to correct a single error out of the three billion "letters" of our genetic code.

They researchers made embryos to remove the disease beta-thalassemia, which the embryos were not implanted.

The team says the approach may one day treat a range of inherited diseases.
Base editing alters the fundamental building blocks of DNA: the four bases adenine, cytosine, guanine and thymine.
They are commonly known by their respective letters, A, C, G and T.


All the instructions for building and running the human body are encoded in combinations of those four bases. The potentially life-threatening blood disorder beta-thalassemia is caused by a change to a single base in the genetic code - known as a point mutation[/http://www.samuelcyprial.com.ng/2017/09/chinese-researchers-has-correct-genetic.html]
