0 a set of related events in which each event causes the next one, or a chemical reaction in which each change causes another:
1 a set of related events in which each event causes the next one:
2 a series of nuclear reactions in which neutrons (= part of an atom) released by fission (= the dividing of an atom) go on to cause more fission
Following isolation, we used polymerase chain reaction in order to generate strain specific banding profiles of legionella isolates.
Experimental infections of rabbits with rabbit haemorrhagic disease virus monitored by polymerase chain reaction.
Plasmodium falciparum : a simple polymerase chain reaction method for differentiating strains.
The great technical problem of such a system is the critical mass of a fission chain reaction, making it difficult to miniaturize a fission explosion.
Thus, typically of a chain reaction, either interstellar panspermia has proceeded to completion or it has not taken place at all.
Following polymerase chain reaction amplification, the product was separated via electrophoresis on 1% agarose gel containing ethidium bromide.
We posit that conduct problems interfere with this development of competencies, thus causing a developmental chain reaction of failures.
The role of environmental contamination with small round structured viruses in a hospital outbreak investigated by reversetranscriptase polymerase chain reaction assay.
