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.
