In this paper, we describe a production procedure of the one-to-one double helical complex of poly(dG)-poly(dC), characterized by a well-defined length (up to 10 kb) and narrow size distribution of molecules. Direct evidence of strands slippage during poly(dG)-poly(dC) synthesis by

Supercoiled plasmid DNAs (at bacterial superhelical density) harboring the homopurine-homopyrimidine sequence, poly(dG)-poly(dC), were reacted with bromoacetaldehyde (BAA), a reagent that reacts with unpaired DNA bases. Not only did the poly(dG)-poly(dC) sequence react with BAA but, surprisingly, neighboring sequences located 3'
