Type IV  
This process is coupled to MAGE  (mage)  in the name of a technique used in 2011 to engineer a whole synthetic genome lacking a stop codon. The  tra   (TRAH)  protein family forms a relaxosome to nick DNA during this process. Type IV  (four)  secretion systems are homologous to the proteins used in it. Joshua Lederberg discovered this process's mechanism, which requires either an F-positive cell or an Hfr  (H-F-R) strain that has the fertility factor chromosomally integrated. This process (*)  spreads R factors, which encode antibiotic resistance. During this process, a pilus forms between two bacteria, enabling horizontal gene transfer that's distinct from transduction and transformation. For 10 points, name this process often analogized to "bacterial sex".
