The 2020 Nobel Prize in Chemistry went to Emmanuelle Charpentier and  Jennifer Doudna for "for the development of a method for genome  editing”. Their work has markedly added to the toolbox available to  researchers in the life sciences and in my humble opinion, it is worth  talking about. To understand why this work is so important, we will need  to have some introductory episodes first and this here is part number II, where we will discuss how genetic information stored in DNA is transformed into biological functions and traits.
