The following points highlight the 3 modes of gene transfer and hereditary recombination in bacteria. The modes are: 1. Transformation 2. Transduction 3. Bacterial Conjugation.
Mode no. 1. Change:
Historically, the breakthrough of change in germs preceded one other two modes of gene transfer. The experiments carried out by Frederick Griffith in 1928 suggested for the time that is first a gene-controlled character, viz. Development of capsule in pneumococci, could possibly be used in a non-capsulated selection of these germs. Verder lezen
