yeast rna polymerase iii is readily distinguished from yeast polymerase i by its biphasic amnonium sulfate activation profile with native dna templates , greater enzymatic activity with poly [ d ( i-c ) ] than with native salmon sperm dna , and distinctive chromatographic elution positions from deae-cellulose ( 0.12 m ammonium sulfate ) compared with deae-sephadex ( 0.32 m ammonium sulfate ) .
