For 10 points, name these common cloning vectors, often consisting of circular non-nuclear DNA fragments, the best known of which are F, which initiates conjugation, and R, used to confer antibiotic resistance.
One of these objects denoted JM1 regulates iron uptake, and the Rep/STB system is responsible for partitioning another of these objects, 2µm, between mother and daughter cells in yeast.  Clowes divided one class of these objects into "stringent" and "relaxed," and a meeting in a Honolulu delicatessen led to Cohen and Boyer's agreement to collaborate on several experiments advancing their study, including the (*) cleavage of SC101 by the restriction enzyme EcoRI.  A process involving sex pili, conjugation, allows organisms to transfer these objects.
