What is transduction in bacteria?
Quick Answer
Transduction is gene transfer between bacteria mediated by a bacteriophage. A virus accidentally carries bacterial DNA from one cell to another.
The Full Story
In transduction, a bacteriophage infects a bacterium and during its life cycle can pick up fragments of bacterial DNA. When the phage infects another bacterium, it may deliver that DNA into the new host. This can transfer genes such as antibiotic resistance or toxin genes. Transduction is a major route of horizontal gene transfer and an important force in bacterial evolution.
Key Facts
1.Uses a bacteriophage as the carrier
2.Transfers bacterial DNA between cells
3.Can spread toxin and resistance genes
