Gene Transfer Mechanism in Bacteria and It’s types

By Acharya Tankeshwar •  Updated: 06/14/21 •  2 min read

In a bacterial population, DNA can be transferred from one organism to another by the horizontal transfer mechanism (apart from vertical inheritance). The DNA thus transferred by lateral/horizontal method can be stably incorporated in the recipient, and changes the genetic composition of the recipient permanently.

Three broad mechanisms mediate the efficient movement of DNA between cells- conjugation, transduction, and transformation.

  1. Conjugation: Transfer of genes between cells that are in physical contact with one another
  2. Transduction: Transfer of genes from one cell to another by a bacteriophage
  3. Transformation: Transfer of cell-free or “naked” DNA from one cell to another
