Only genes in the same chromosomal vicinity can be transformed; the closer together the genes lie, the more frequently they will be cotransformed. By contrast, genes sufficiently far apart that they cannot appear together on a fragment of foreign DNA will almost never be cotransformed, because transformation is so inefficient that recipient cells usually take up only a single DNA. capota jeepWebFeb 6, 2014 · As a rule, plasmids from the same group should not be co-transformed, so if you need two plasmids for an experiment, make sure they have "compatible" ori's.
