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.

Gene Transfer Mechanism in Bacteria

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

Transduction

Transformation
