Interrupted mating experiments were performed using three different Hfr strain (1-3). The three strains have different combinations of selectable markers, the time of entry for markers for each strain is shown in the table below Strain Time of entry Hfr#1 Met(5') Thr(17') Str(25') Phe(30') Hfr#2 Str(15') Pur(28') Pro(35') His(45') Hfr#3 Pro(2') His(12') Met(22') Phe(47') using the data find the correct sequence of data on the E Coli. a) Met-Thr-Str-Phe-Pro-Pur^r-His b)Pur^r-Pro-His-Met-Thr-Str^r-Phe c)Str^r-Pur^r-His-Met-Phe-Pro-Str^r d)His-Met-Phe-Thr-Pro-Str^r-Pur^r
