Three Hfr strains of E. coli, each with genotype StarS, lacZ, A, B, C, D are mated to an F- strain with the genotype StrR, lacZ-, a, b, c, d. Samples of conjugating strains are collected and disrupted every minute for one hour using a blender. Cells are plated under conditions that allow the lacZ , A, B, C, and D alleles to be identified. The time at which each dominant allele is transferred is shown. lacZ A B C DHfr1 50' 5' 15' 40'Hfr2 2' 47' 70' 37' 12'Hfr3 45' 15' 55'Considering that some variation exists between bacterial strains in the overall size of their chromosome (in min), how many minutes are in the complete genome of this strain?A) 85.B) 88.C) 93.D) 98.
