An E. coli strain has metB1 (90 min) and leuA5 (2 min) mutations. It also has strA7 (73 min) mutation and Tn5 transposon which confers streptomycin and kanamycin resistance, respectively, inserted in its chromosome. The mutant strain was crossed with an Hfr strain that is streptomycin sensitive and has a hisG2 mutation (44 min) that makes it require histidine. After incubation for 100 min, the cells were plated on minimal plate supplemented with leucine, histidine and streptomycin to select the metB marker. After purifying 100 of the Met transconjugants, one finds that 15 are His+, 2 are Leu" and 12 are kanamycin sensitive. The unselected markers are A. metB1 and leuA5 mutation. B. leuA5 and Tn5 insertion mutation. Which of the above statement is correct and what is the position of transposon insertion? (1) A and before 73 min (2) B and before 44 min (3) B and before 73 min (4) A and before 44 min
