Transformation: Mode of genetic transfer in which “bare DNA” is taken up from the environment is taken up by cells

Transduction: Mode of genetic transfer in which genes are transferred by a bacteriophage to a bacterial cell

Conjugation: Mode of genetic transfer in which two cells must come in contact and genetic material is transferred to a recipient cell from a donor cell through its pili
