Three kinds of genetic transfer occur in bacteria Transformation: donor cell releases dNa by lysi S and it is taken up by the recipient cell Conjugation: physical contact between two bacterial cells and transfer of dna Transduction: bacterial virus(phage) transfers the DNa from donor cell to recipient cellThree kinds of genetic transfer occur in bacteria • Transformation: donor cell releases DNA by lysis and it is taken up by the recipient cell • Conjugation: physical contact between two bacterial cells and transfer of DNA • Transduction: bacterial virus (phage) transfers the DNA from donor cell to recipient cell
