Sticky ends on DNA are formed by action of enzymes restriction endonucleases. These enzymes cut the strand of DNA a little away from the centre of the palindrome  sequence between the same two bases on both the strands. This results in single stranded stretches on both the complementary strands at their ends.

These overhanging stretches are called sticky ends as they form hydrogen bonds with the complementary base pair sequences.
