WebTransformation is often used to describe non-viral DNA transfer in bacteria, non‑animal eukaryotic cells, and plant cells.However, transformation also refers to a particular event or a series of events that results in a permanent change in an animal cell’s phenotype, and implies genetic instability and a progression to a cancerous state. WebIn addition to these methods, a conceptually novel transformation technique, namely the hydrogel exposure method, was developed. The hydrogel exposure method, based on the Yoshida effect, provides a significant advance over chemical means for transforming many strains of Escherichia coli and a variety of other bacterial species.
