Question

describe the gene transfer process in bacteria

Answer 1

Transduction, the process in whichbacterial DNA is moved from onebacterium to another by a virus (a bacteriophage, or phage). Bacterialconjugation, a process that involves the transfer of DNA via a plasmid from a donor cell to a recombinant recipient cell during cell-to-cell contact.

Answer 2

In bacterial population DNA can be transferred from one organism to other 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 recipient permanently.


Movement of DNA between cells-

Conjugation: The transfer of genes between cells which are in phsical contact with one another.

Transduction: Transfer of genes from one cell to another by a bacteriophage.

Transformation: Transfer of cell-free or naked DNA from one cell to another.
