hi
transformation
Yes, although it hasn't been observed in nature. Scientists have been able to artificially insert a gene into a bacteria using sticky ends of the plasmids and DNA ligase to hold them together, thereby inserting a gene into the bacterial chromosome.
The only reason that scientists use bacterial DNA rather than human DNA is because bacterial DNA is much more simpler and can reproduce unbelievably quick.

A recombinant plasmid gets inside a bacterial cell by
Transformation.
The process of adding foreign DNA to a bacterial cell is called Bacterial Transformation. It is a technique used very frequently in molecular Biology labs.Ê

== == transformation ------------------------------------------------------------------------------------------------------- Transformation is the process in which a bacteria takes in DNA from the environment. Reference: http://en.wikipedia.org/wiki/Transformation_(genetics) By the way, transduction is the process of DNA transfer by the action of a virus (bacteriophages). The other method of DNA exchange between bacteria is called conjugation, which is the transfer of DNA between bacteria by physical contact.
In molecular biology, transformation is the genetic alteration of a cell resulting from the direct uptake and incorporation of exogenous genetic material (exogenous DNA) from its surroundings through the cell membrane(s). Transformation occurs naturally in some species of bacteria, but it can also be effected by artificial means in other cells

Basically, transformation refers to the uptake and incorporation of naked genetic material by a competent cell. Most bacterial cells are not naturally competent(able to take up naked genetic material). The kinds that are use a type 4 pilli to get the genetic material into the cell. This process is very rare in nature, since it requires naked genetic material to be present, from a lysed cell, as well as a competent cell to take up the genetic material. When the DNA/RNA is taken up, it is often degraded by restriction enzymes. If it is not degraded it can exist as extra chromosomal DNA, much like a plasmid, or it can be incorporated into the cells chromosome. Scientists use heat, pH, or osmotic shock in lab to make cells artificially competent.
