electrophoretic analysis , dnase protection experiments and observations by electron microscopy suggest that saturated reca complexes formed with single- or double-stranded dna are able to accommodate an additional single strand of dna with a stoichiometry of about one nucleotide of added single-stranded dna per nucleotide or base-pair , respectively , of dna resident in the complex .
