Generalized Transduction Notes

Generalized Transduction

  • Generalized transduction is a process where DNA is transferred from one bacterial cell to another via a bacteriophage (or phage).

  • The phage, a bacterial virus, attaches to a bacterial cell.

  • It injects its nucleic acid into the host cell.

  • A phage-produced enzyme then breaks down the host cell's DNA into smaller fragments.

  • Phage DNA replicates and phage proteins are produced.

  • During the assembly of mature phage particles, some phage heads mistakenly encapsulate fragments of bacterial DNA instead of phage DNA.

  • A phage particle containing bacterial DNA infects a new cell.

  • This transfers the bacterial DNA to the new host cell.

  • The introduced bacterial DNA can integrate into the recipient cell's chromosome.

  • This integration transfers genes to the recipient cell.

  • The recipient cell multiplies, now carrying the new genetic material.
