Transduction

Definition

The process by which DNA is transferred from one bacterium to another by a virus (bacteriophage). It plays a crucial role in bacterial genetic variation and evolution.

5 Must Know Facts For Your Next Test

1. Transduction involves the transfer of DNA via bacteriophages.
2. There are two types of transduction: generalized and specialized.
3. Generalized transduction can transfer any part of the donor's genome.
4. Specialized transduction transfers only specific parts of the donor's genome.
5. This mechanism contributes to genetic diversity among prokaryotic populations.
