Sticky ends can be converted to blunt ends by a process known as blunting, which involves filling in the sticky end with complementary nucleotides. This yields a blunt end, however, sticky ends are often preferable, meaning the main use of this method is to label DNA by using radiolabeled nucleotides to fill the gap. [ 4 ]
Blunt-end ligation, however, is much less efficient than sticky end ligation, typically the reaction is 100X slower than sticky-end ligation. Since blunt-end does not have protruding ends, the ligation reaction depends on random collisions between the blunt-ends and is consequently much less efficient.
Sticky ends of DNA however are more likely to successfully bind with the help of a DNA ligase because of the exposed and unpaired nucleotides. For example, a sticky end trailing with AATTG is more likely to bind with a ligase than a blunt end where both the 5' and 3' DNA strands are paired. In the case of the example the AATTG would have a ...
A restriction enzyme or restriction endonuclease is a special type of biological macromolecule that functions as part of the "immune system" in bacteria.One special kind of restriction enzymes is the class of "homing endonucleases", these being present in all three domains of life, although their function seems to be very different from one domain to another.
EcoRI digestion produces "sticky" ends, whereas SmaI restriction enzyme cleavage produces "blunt" ends: Recognition sequences in DNA differ for each restriction enzyme, producing differences in the length, sequence and strand orientation (5' end or 3' end) of a sticky-end "overhang" of an enzyme restriction.

By the end of our relationship, I’d kiss the scars as foreplay and stuff (that was over the course of a couple years and was very much consensual, I wouldn’t just jump straight to scar-play lol).
DNA ligase can ligate complementary sticky and blunt ends, but blunt-end ligation is inefficient and requires a higher concentration of both DNA and DNA ligase than the ligation of sticky ends does. [6] For this reason, most restriction enzymes used in DNA cloning make staggered cuts in the DNA strands to create sticky ends.
Blunt shared that the energy in the room shifted when Gosling took the stage. “The energy in the room when he started doing it, it just lifted the whole thing,” she said.
