Primero se sintetizan dos oligonucleótidos, que sean complementarios a la secuencia diana completa, uno por el extremo 5’ y el otro por el 3’. Si la secuencia diana se encuentra en la muestra de ADN que se está examinando, los oligonucleótidos se fijan a ella reuniendo sus extremos en el centro y, mediante una ligasa termoestable, se unen para formar un polinucleótido completo. El ligamiento no se producirá si la muestra no contiene la secuencia diana o si el empalme entre la secuencia diana y los oligonucleótidos es imperfecto. Sometido a una temperatura elevada, el nuevo polinucleótido se disocia del molde de ADN original; después de bajar la temperatura, éste y el ADN original servirán de moldes para un segundo ciclo de hibridación, ligamiento y disociación térmica.

Pyrolysis, also termed thermolysis (Greek: pur = fire; thermos = warm; luo = loosen), is a process of chemical and thermal decomposition, generally leading to smaller molecules. Semantically, the term thermolysis is more appropriate than pyrolysis, since fire implies the presence of oxygen and hence of reactive and oxygen-bearing intermediates. In most pyrolysis processes, however, air is excluded, for reasons of safety, product quality, and yield. 3, record 4, English, - thermolysis

Cyanide toxicity is caused by the free cyanides (HCN and CN-) that inhibit cytochrome oxidase and thereby suppress aerobic respiration. Fish are the most susceptible organisms - sensitive species exhibit chronic and lethal effects at as low as 5-7 and 20-76 grams/liter, respectively. The toxicity of complex cyanides is usually, but not always, low, but the degradation products often include free cyanides which are toxic. Free cyanides readily degrade in the open environment but persist in groundwater. They do not bioaccumulate. Sublethal effects in fish include reduced reproductive capacity (decreased egg number and viability, and reduced embryo and larval survival), impaired swimming ability, altered growth, and hepatic necrosis. Free cyanides are phytotoxic at higher concentrations than those associated with adverse effects in fish. 2, record 6, English, - free%20cyanide
