Exactly about Gene Transfer and Genetic Recombination in Bacteria

The following points highlight the three modes of gene transfer and recombination that is genetic germs. The modes are: 1. Transformation 2. Transduction 3. Bacterial Conjugation.

Mode no. 1. Change:

Historically, the finding of change in germs preceded the other two modes of gene transfer. The experiments carried out by Frederick Griffith in 1928 suggested for the very first time that a gene-controlled character, viz. Development of capsule in pneumococci, could possibly be utilized in a non­-capsulated number of these germs. The transformation experiments with pneumococci ultimately resulted in a similarly significant development that genes are constructed with DNA.
