Abortive initiation by bacteriophage T3 and T7 RNA polymerases under conditions of limiting substrate

Abstract

Nucleic Acids Research, 17, 1605-1618 (1989)The Figure 2 legend should read:. In order, from left to right, the Concentrations of these substrates were 400, 200, 100, 50. 25, and 12.5 μM.The Figure 3 legend should read:. Unless otherwise noted the concentration of all ribonucleoside triphosphates was 400 μM: in lanes marked C or U the concentration of CTP or UTP was 10 μM.The Figure 4 legend should read:. Panel A. Hae II restriction fragments of T7 DNA (0.25 μg) were incubated with a four-fold or eight-fold molar excess of RNA polymerase, as indicated by the numbers above the lane.The column headings in Table I should read:. UTP concn (μM). CTP eonn (μM). © 1989 IRL Press at Oxford University.
