reinitiation efficiencies , as assessed by beta-galactosidase levels in strains bearing such plasmids , appear to be determined by at least three features of the rna between the termination codon and reinitiation codon : the presence of competing out-of-frame aug or gug triplets , the distance between termination and reinitiation points , and the extent to which restart sequences remain accessible to ribosomes .
