Horizontal Gene Transfer in Bacteria

Bacterial Transformation: Mechanism

Bacterial Transformation: Mechanism

Process of random uptake of free DNA fragments by the competent bacteria from the surrounding environment.

Conjugation: Transfer of Chromosomal DNA by HFr Strains

Conjugation: Transfer of Chromosomal DNA by HFr Strains

Donor cells in which F factor are integrated can transfer adjacent chromosomal gene to recipient cells in a high frequency.

Mechanism of Conjugation in Bacteria: The transfer of F Plasmid

Mechanism of Conjugation in Bacteria: The transfer of F Plasmid

Transfer of genetic material from one bacteria (male) to another bacteria (female) through mating (via conjugation tube made by sex pili).

Gene Transfer Mechanism in Bacteria and It’s types

Gene Transfer Mechanism in Bacteria and It’s types

Three broad mechanisms mediate the efficient movement of DNA between cells- conjugation, transduction, and transformation.

Specialized transduction: Mechanism

It involves transfer of only a particular genetic segment of the bacterial chromosome that is present adjacent to the phage DNA.

Generalized transduction: Mechanism

Generalized transduction: Mechanism

Transfer of any part of the donor bacterial genome into the recipient bacteria with the help of bacteriophage.
