Two scientists have been awarded the 2020 Nobel Prize in Chemistry for developing the tools to edit DNA.
Emmanuelle Charpentier and Jennifer Doudna are the first two women to share the prize, which honours their work on the technology of genome editing.
Their discovery, known as Crispr-Cas9 “genetic scissors”, is a way of making specific and precise changes to the DNA contained in living cells.
They will split the prize money of 10 million krona (£861,200; $1,110,400).
Biological chemist Pernilla Wittung-Stafshede, commented: “The ability to cut DNA where you want has revolutionised the life sciences.”
Not only has the women’s technology been transformative for basic research, it could also be used to treat inherited illnesses.
Prof Charpentier, from the Max Planck Unit for the Science of Pathogens in Berlin, said it was
