<prompt> Which statement concerning plasmids is trueAll plasmids possess the information for their own transfer by conjugationMuch of the information coded in the plasmid is essential to the survival of the bacteria cellR plasmids carry genes for antibiotic resistanceR plasmids cannot be transferred to other bacterial cells  <response>: Plasmids are small, circular, supercoiled DNA molecules found in some bacteria. They usually do not carry essential genes, but some plasmids, such as R resistance plasmids, carry genes coding for antibiotic resistance. All plasmids have their own origin of replication, so that they are replicated along with the host chromosome and passed along to progeny cells. Only some plasmids possess genes that allow for their transmittal to other bacteria by the process of conjugation.
