Step 1

Conjugation: Bacteria can transfer genetic information through a process called conjugation. During conjugation, two bacteria physically connect through a structure called a pilus. One bacterium, called the donor, transfers a small circular piece of DNA called a Show more…

Key Concepts

Conjugation

Conjugation is one mechanism of horizontal gene transfer where bacteria directly transfer genetic material, usually in the form of plasmids, via physical contact using structures such as pili. This process enables efficient dissemination of genetic traits within and between bacterial species.

Transformation

Transformation is the process by which bacteria take up free fragments of DNA from their environment. This uptake allows bacteria to integrate new genetic information into their genomes, potentially granting them new capabilities or traits.

Horizontal Gene Transfer

Horizontal gene transfer is the movement of genetic material between bacteria (or other organisms) that is not inherited from parent to offspring. It is a central concept in microbiology for explaining how bacteria rapidly acquire new traits, such as antibiotic resistance, and adapt to changing environments.

Transduction

Transduction is a mechanism that involves bacteriophages, which are viruses that infect bacteria. These viruses inadvertently transfer pieces of bacterial DNA from one cell to another during the infection process, contributing to genetic diversity among bacterial populations.
