The following points highlight the 3 modes of gene transfer and recombination that is genetic bacteria. The modes are: 1. Transformation 2. Transduction 3. Bacterial Conjugation.
Mode number 1. Transformation:
Historically, the finding of change in germs preceded one other two modes of gene transfer. The experiments conducted by Frederick Griffith in 1928 suggested when it comes to time that is first a gene-controlled character, viz. Development of capsule in pneumococci, might be utilized in a variety that is non-capsulated of germs.
