Abstract
The triplex structure in vitro is well established; however, no direct evidence has been available concerning its existence in the cell. Using the direct chemical probing here we show that the triplex H structure can exist in E. coli cells at acidic intracellular pH values; this structure differs in some details from that observed in vitro.Keywords
