	Encyclopedia: Annealing
		Annealing (biology), in genetics, DNA or RNA pairing by hydrogen bonds to a complementary sequence, forming a double-stranded polynucleotide.
		Annealing (metallurgy), a heat treatment wherein the microstructure of a material is altered, causing changes in its properties such as strength and hardness.
		Annealing, in glassblowing and lampworking, is heating a piece of glass until its temperature reaches a stress-relief point, that is, a temperature at which the glass is still too hard to deform, but is soft enough for internal stresses to ease.

	BCH5425 Molecular Biology and Biotechnology
		The calculated annealing temperature is only a reference temperature from which to initiate experiments.
		The molar extinction coefficient for the primer can be calculated by knowing the sequence of the primer and then summing the molar extinction values for the individual bases which comprise the primer.
		For example, the primer 5' TAGC 3' would have a molar extinction coefficient of 42,660 at 260 nm.

	Real-Time PCR [M.Tevfik DORAK]
		When the beacon hybridises to the target during the annealing step, the reporter dye is separated from the quencher and the reporter fluoresces (FRET does not occur).
		Molecular beacons also contain fluorescent (FAM, TAMRA, TET, ROX) and quenching dyes (typically DABCYL) at either end but they are designed to adopt a hairpin structure while free in solution to bring the fluorescent dye and the quencher in close proximity for FRET to occur.
		Molecular beacons remain intact during PCR and must rebind to target every cycle for fluorescence emission.

		Such an approach may have benefits for engineering, by leading to the construction of better-performing robots, and for biology, by allowing real-time and real-world tests of critical hypotheses about how locomotor control is effected.
		By using simulated annealing optimization, it is shown that optimally heterogeneous nets actually cluster around the same narrow domain, suggesting that strong constraints actually operate on the possible universe of complex networks.
		Engineers have begun to team with neurobiologists to build walking robots whose physical design and functional control are based on insect biology.

		To solve the program we use``replicator'' equations, a class of simple continuous- and discrete-time dynamical systems developed in various branches of theoretical biology.
		We show how, despite their inability to escape from local solutions, they nevertheless provide experimental results which are competitive with those obtained using more elaborate mean-field annealing heuristics.
		The approach is centered around a remarkable result proved by Motzkin and Straus in the mid-1960s, and recently expanded in various ways, which allows us to formulate the maximum clique problem in terms of a standard quadratic program.

		To solve the program we use the so-called replicator equations--a class of straightforward continuous- and discrete-time dynamical systems developed in various branches of theoretical biology.
		We show how, despite their inherent inability to escape from local solutions, they nevertheless provide experimental results that are competitive with those obtained using more elaborate mean-field annealing heuristics.
		The attractive feature of this formulation is that a clear one-to-one correspondence exists between the solutions of the quadratic program and those in the original, combinatorial problem.

	Genetic algorithm - Wikipedia, the free encyclopedia
		Tabu search (TS) is similar to Simulated Annealing, in that both traverse the solution space by testing mutations of an individual solution.
		Genetic algorithms are a particular class of evolutionary algorithms that use techniques inspired by evolutionary biology such as inheritance, mutation, natural selection, and recombination (or crossover).
		In each generation, the fitness of the whole population is evaluated, multiple individuals are stochastically selected from the current population (based on their fitness), modified (mutated or recombined) to form a new population, which becomes current in the next iteration of the algorithm.

	Genetic algorithm - Wikipedia, the free encyclopedia
		Genetic algorithms are a particular class of evolutionary algorithms that use techniques inspired by evolutionary biology such as inheritance, mutation, natural selection, and recombination (or crossover).
		Memetic Algorithm is a term that is used by some researchers to define forms of genetic algorithm that are combined with other forms of local search, such as simulated annealing.
		As a general rule of thumb genetic algorithms might be useful in problem domains that have a complex fitness landscape as recombination is designed to move the population away from local minima that a traditional hill climbing algorithm might get stuck in.

		The advent of Polymerase Chain Reaction (PCR) by Kary B. Mullis in the mid-1980s revolutionized molecular biology as we know it.
		The more times the denaturing and annealing takes place, the more opportunities there are for the Taqman® probe to bind and, in turn, the more emitted light is detected.
		Clearly, PCR is a procedure that is an integral addition to the molecular biologist’s toolbox, and the method has been continually improved upon over the years.

		This was accomplished by investigating the impact of increasing the number cycles, increasing the amount of primer, increasing the primer GC content, increasing the reaction annealing temperature, and examining the relationship between primer location to predicted template secondary structure.
		An octamer primer library was used to facilitate sequence analysis of transcripts expressed in adult Drosophila brain.
		This sequencing strategy is faster than a traditional primer-walking strategy, since access to this optimized octamer library eliminates delays associated with designing and synthesizing gene specific primers.
