Exactly about Gene Transfer and Genetic Recombination in Bacteria

The following points highlight the 3 modes of gene transfer and hereditary recombination in germs. The modes are: 1. Transformation 2. Transduction 3. Bacterial Conjugation.

Mode no. 1. Transformation:

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