nonconjugative plasmid

a non-transmissible PLASMID, which cannot mediate CONJUGATION. Non-conjugative plasmids lack transfer (tra) genes, which are present on CONJUGATIVE PLASMIDS. However, they can sometimes be co-transferred with appropriate CONJUGATIVE PLASMIDS, when co-residing in the same cell. Usually smaller than CONJUGATIVE PLASMIDS.
