Abstrakt: Summary The RNase hydrolysis of random-coil (alkaline form) poly A follows biphasic kinetics at low salt concentrations. However, its resistance to RNase increases with the ionic strength. Helical (acidic form) poly A is also susceptible to RNase but its hydrolysis follows first-order kinetics, and its resistance increases as the pH is lowered. These conformation-dependent kinetics of poly A hydrolysis are similar to those obtained in the hydrolysis of cellular RNA and reovirus double-stranded RNA.
