The DNA transformation is the horizontal transfer of DNA in which the DNA is taken up by the competent bacterial cells from the surrounding.
The transformation process was studied by the Griffith in 1928 in <em>Streptococcus pneumoniae</em>- R and S- strains in which R-strain bacteria took the DNA from the surrounding environment and became S-strain.
The cells become competent by changing their cell wall composition and take DNA after which the DNA gets integrated with the genome of the bacteria through homologous recombination.
