If a restriction enzyme has a cleavage site consisting of six nucleotide pairs, what is the chance that six adjacent nucleotides in a random sequence of double-stranded DNA will match the restriction site? A)(1/2)⁴ = 1/16 B)(1/2⁾⁶ = 1/64 C)(1/4)⁴ = 1/256 D)(1/4)⁶ = 1/4096

For each nucleotide pair, there are 4 possibilities (A-T, T-A, G-C, C-G), so the chance for one specific pair is 1/4. For six pairs, it's (1/4)^6 = 1/4096.
