Q1: What’s the difference between random mutagenesis and DNA shuffling?

Random mutagenesis is the most straightforward strategy for library construction, in which the full gene of an enzyme is randomly mutated. The desired function is then obtained by targeted selection. This approach requires no structural or mechanistic information, and can uncover unexpected beneficial mutations. Although random mutagenesis technique is a relatively simple and easy-to-conduct approach, the frequency of gaining beneficial mutations is generally low. In addition, random mutation may lead to either a library too large to screen successfully or to incorporation of mutations that lead to loss of functions. Gene shuffling can overcome the limitations by allowing a large number of beneficial mutations from multiple genes to be incorporated at a single step of the library creation process.
