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 ...
These sticky ends can anneal to other compatible ends and become ligated in a sticky-end (or cohesive end) ligation. EcoRI for example generates an AATT end, and since A and T have lower melting temperature than C and G, its melting temperature T m is low at around 6 ° C. [21] For most restriction enzymes, the overhangs generated have a T m ...

Protruding ends—both 3' and 5'—are sometimes called "sticky ends" because they tend to bond with complementary sequences of bases. In other words, if an unpaired length of bases 5'—AATT—3' encounters another unpaired length with the sequence 3'—TTAA—5' they will bond to each other—they are "sticky" for each other.
[14] Compare derived terms such as monadelphous, having stamens growing in a single bunch or tube, for example in Hibiscus, and diadelphous, growing in two bunches. adherent Slightly united to an organ of another kind, [ 13 ] usually to a part of another whorl, e.g. a sepal connected to a petal .
Blunt ends are much less likely to be ligated by a DNA ligase because the blunt end doesn't have the overhanging base pair that the enzyme can recognize and match with a complementary pair. [3] 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.

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 ...
