WebApr 12, 2024 · C. necator strains were transformed with plasmids in a two-step method in which the plasmids were first transformed to chemically competent E. coli WM3064 cells by heat shock, followed by conjugation of the plasmid from the WM3064 donor strain to C. necator. Strain WM3064 was a gift from William Metcalf (University of Illinois). WebKey points: In transformation, a bacterium takes up a piece of DNA floating in its environment. In transduction, DNA is accidentally moved from one bacterium to another by a virus. In conjugation, DNA is transferred between bacteria through a tube between cells. Transposable elements are chunks of DNA that "jump" from one place to another.

In order for plasmids to replicate independently within a cell, they must possess a stretch of DNA that can act as an origin of replication. The self-replicating unit, in this case, the plasmid, is called a replicon.
