In 2019, Liu, who is also an author of the Nature Biotechnology study, developed a technique called prime editing, which enables any kind of point mutation to be introduced, as well as insertions and deletions.

Even so, scientists still don’t know how long a proton would need to stay in its unstable position for such a point mutation to actually occur, Hay noted.

It needs only one point mutation to develop resistance to certain antiviral drugs, and such mutations happen all the time.

Amplifications of both c-Ki-ras with a point mutation and c-myc in a primary pancreatic cancer and its metastatic tumors in lymph nodes.

Errors in the genetic code in which one pair swaps for another, a change called a point mutation, can be disastrous.
