Transduction (genetics)
Transduction (genetics)
Transduction is a process in genetics where bacteria transfer genetic material from one bacterium to another through a bacteriophage, which is a type of virus that infects bacteria. This process is one of the three basic mechanisms that bacteria use to exchange genetic material, the other two being transformation and conjugation.
Pronunciation
Transduction is pronounced as /trænsˈdʌkʃən/.
Etymology
The term "transduction" comes from the Latin word "transducere", which means "to lead across" or "to transfer". In the context of genetics, it refers to the transfer of genetic material from one bacterium to another.
Types of Transduction
There are two types of transduction: Generalized transduction and Specialized transduction.
In generalized transduction, any part of the bacterial genome can be transferred from one bacterium to another. This occurs during the lytic cycle of virulent phages.
In specialized transduction, only specific parts of the bacterial genome are transferred. This occurs during the lysogenic cycle of temperate phages.
