Web3.2.2.1 Exon shuffling. In vitro exon shuffling method was first described by Kolkman and Stemmer53. This method creates new genes by combining two or more exons from different genes or by duplicating the same exon. This method starts with creating DNA fragments containing either exons or a combination of exons of a eukaryotic gene. flip ncfmWebJun 19, 2024 · Natural Selection. Katherine Harris.
