Some restriction enzymes cut at specific and unambiguous sequences (e. g., noti at gcggccgc). as such, the distance between two such sites in a large random dna sequence is 48, assuming a 50% g+c dna content. however, the sequence recognized by xhoii is said to be ambiguous (pu-gatc-py, where pu = any purine and py any pyrimidine). what, therefore, is the expected distance between two xhoii sites in a large random sequence? a) 4 Γ 4 Γ 4 Γ 4b) 1 Γ 4 Γ 4 Γ 4 Γ 4 Γ 1c) 2 Γ 4 Γ 4 Γ 4 Γ 4 Γ 2d) 46e) 42 Γ 22
