Note: Only one strand of the target DNA is shown, in the interests of clarity. It will be noted that the omitted strand has the same sequence as the one show, but the nucleotides occur in the reverse order. Thus for example The complementary sequence for Sal I (with its point of cleavage indicated as above) is 5' -C A G C T * G-3'. These are hence said to be palindromic sequences, and double-stranded cuts produce short sinlge-stranded cohesive ends.
