For a P1 transduction experiment,an E.coli donor strain with the genotype arg+,ser+,ampR and a recipient strain with the genotype arg-,ser-,ampS were used.The following results were obtained for each marker:
Of the transductants selected for arginine,5% are ser+ and 30% are ampR.
Of the transductants selected for serine,3% are arg+ and 0% are ampR.
What is the correct order and relative distance of these three genes on the E.coli chromosome?
