translation in a rabbit reticulocyte lysate system of polysomal and cytoplasmic mrnas from the three sublines has shown that the overproduction of dihydrofolate reductase by resistant cells is accompanied by increased levels of dihydrofolate reductase-specific mrna and that the different molecular weight forms of dihydrofolate reductase are encoded by their respective mrnas .
