How are ‘Sticky ends’ formed on a DNA strand? Why are these so-called?
Restriction enzymes cut the strand of DNA a little away from the centre of palindrome site, but between the same two bases on opposite strands. As a result, single-stranded portions are left at each end. These overhanging stretches of DNA are called ‘Sticky ends’. 2. The Sticky ends are named so because they form hydrogen bonds with their complementary cut counterparts. The stickiness helps in the action of DNA ligase.
