Three processes that occur in nature that allow an E.coli cell to have new DNA sequences not found in its parent cell are : Transduction, transformation and conjugation
Transduction, transformation and conjugation are the recombination strategies used by E.coli to expand their genetic variety.
Process by which DNA is transferred from one bacterium to another by a virus is called transduction. It also refers to the process where foreign DNA is introduced into another cell through a viral vector.
In transformation, bacterium takes up a piece of DNA floating in its environment and in conjugation, DNA is transferred between bacteria via a tube between cells.
