1.	An antibiotic resistance gene in a vector usually helps in the selection ofA. competent cellsB. transformed cellsC. recombinant cellsD. None of these
Answer» Selectable markers help in identifying and elminating non-transofrmants selectively permiting the growth of the transformation . The normal E, coli cells do carry resistance against any of these antiobiotics. Completant bacterial cells are no capable to take foreign DNA with chemical treatment, e.g., calcium chloride.
