anneal

anneal

 [ah-nēl´]
1. to heat a material, such as glass or metal, followed by controlled cooling to remove internal stresses and induce a desired degree of toughness, temper, or softness of the material.
2. to homogenize an amalgam alloy ingot by heating it in an oven.
3. to heat a material, such as gold foil, to volatilize and drive off impurities from its surface, and to increase its cohesive properties.

an·neal

(an-nēl'),
1. To soften or temper a metal by controlled heating and cooling; the process makes a metal more easily adapted, bent, or swaged, and often less brittle.
2. In dentistry, to heat gold leaf preparatory to its insertion into a cavity, to remove adsorbed gases and other contaminants.
3. The pairing of complementary single strands of DNA; or of DNA-RNA.
4. The attachment of the ends of two macromolecules, for example, two microtubules annealing to form one longer microtubule.
5. In molecular biology, annealing is a process in which short sections of single-stranded DNA from one source are bound to a filter and incubated with single-stranded, radioactively conjugated DNA from a second source. Where the two sets of DNA possess complementary sequences of nucleotides, bonding occurs. The degree of relatedness (homology) of the two sets of DNA is then estimated according to the radioactivity level of the filter. This technique plays a central role in the classification of bacteria and viruses. Synonym(s): nucleic acid hybridization
6. To renature proteins or polynucleic acids by slow cooling.

If (but only if) the 3' end of primer 1 anneals to the template, an enzyme known as DNA ligase catalyzes the covalent joining of the 3'-OH of primer 1 to the 5' phosphate of primer 2.
Some descriptions of this technique suggest tipping the brass into the water is a necessary part of annealing, but the water merely prevents the casehead from being annealed. We want the case head to remain relatively hard; otherwise a normal load results in a blown case, and maybe a blown gun.

Where no product is formed, the probe cannot anneal and is chemically degraded by the detection procedure without emitting a signal.
