In a 1956 experiment, Jacob and Wollman mapped this process by periodically "interrupting" it using a blender.
In the presence of amino acid derivatives called "opines," an autoinducer activates the genes required for this process in a model organism. In a 1956 experiment, Jacob and Wollman mapped this process by periodically "interrupting" it using a blender. It's not splicing, but this process begins with a transesterification reaction catalyzed at the oriT ("oh-ree-T") site by a Mob relaxase encoded on the Tra operon. Apart from translocation of effector proteins, this is the major ]=function of type IV ("four") secretion systems. R factors encoding antibiotic resistance are spread through this process. In Hfr strains, the genetic material involved in this process is integrated into the chromosome. During this process, two cells become positive for the F plasmid after a sex pilus ("PY-lus") bridges them together. For 10 points, name this form of horizontal gene transfer that requires direct cell-to-cell contact, unlike transduction or transformation.
