DNA ends refer to the properties of the ends of linear DNA molecules, which in molecular biology are described as "sticky" or "blunt" based on the shape of the complementary strands at the terminus. In sticky ends , one strand is longer than the other (typically by at least a few nucleotides), such that the longer strand has bases which are ...
Ligation involves joining up the ends of a DNA with other ends, however, each DNA fragment has two ends, and if the ends are compatible, a DNA molecule can circularize by joining its own ends. At high DNA concentration, there is a greater chance of one end of a DNA molecule meeting the end of another DNA, thereby forming intermolecular ligation.
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.

3' untranslated region (3'-UTR). Also three-prime untranslated region, 3' non-translated region (3'-NTR), and trailer sequence.. 3'-end. Also three-prime end.. One of two ends of a single linear strand of DNA or RNA, specifically the end at which the chain of nucleotides terminates at the third carbon atom in the furanose ring of deoxyribose or ribose (i.e. the terminus at which the 3' carbon ...
Topoisomerase-based cloning (TOPO cloning) is a molecular biology technique in which DNA fragments are cloned into specific vectors without the requirement for DNA ligases.Taq polymerase has a nontemplate-dependent terminal transferase activity that adds a single deoxyadenosine (A) to the 3'-end of the PCR products.
Cas12a leaves one strand longer than the other, creating sticky ends. The sticky ends have different properties than blunt ends during non-homologous end joining or homologous repair of DNA, which confers certain advantages to Cas12a when attempting gene insertions, compared to Cas9. [ 3 ]
The Sticky’s first season finale on Prime Video opens with the trio stuffing Bo’s body into a deep freezer, only she had already alerted Mike’s Boston crime family about his goings-on in Canada.
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.
