A RNA polymerization assay was performed using 3H UTP as the labelled nucleotide with a specific activity of 500 Ci/ mol (1 Ci = 2.2 106 counts per min). After 10 min incubation, the trichloroacetic acid-insoluble radioactivity was found to be 692521 counts per min as determined in a liquid scintillation counter working at 60% efficiency for 3H. The amount of UTP incorporated into the RNA will be
