the relatedness of the coding sequences of the ax- and beta-actin genes is indicated by our finding that pcdd actin itl-i dna , a recombinant plasmid dna that contains a dna sequence complementary to actin mrna of dictyostelium discoideum , hybridizes both the ax-actin mrna and the beta-actin mrna but not the gamma-actin mrna .
