A strip of eight PCR tubes, each containing a 100 μL reaction mixture Placing a strip of eight PCR tubes into a thermal cycler. The polymerase chain reaction (PCR) is a method widely used to make millions to billions of copies of a specific DNA sample rapidly, allowing scientists to amplify a very small sample of DNA (or a part of it) sufficiently to enable detailed study.
The ARL was established in 1945 by the U.S. Navy when the Harvard Underwater Sound Laboratory (USL) was terminated and its torpedo division was moved to Penn State. Eric Walker, the USL's assistant director, moved to Penn State to become its first director from 1945 until 1951, when he became the president of the university.

Template:Craniofacial. Interactive animation of the structure of ATP. Adenosine triphosphate (ATP) is a nucleoside triphosphate [1] that provides energy to drive and support many processes in living cells, such as muscle contraction, nerve impulse propagation, and chemical synthesis.
The history of scientific method considers changes in the methodology of scientific inquiry, not the history of science itself. The development of rules for scientific reasoning has not been straightforward; scientific method has been the subject of intense and recurring debate throughout the history of science, and eminent natural philosophers and scientists have argued for the primacy of ...
Laboratory safety. Many laboratories contain significant risks, and the prevention of laboratory accidents requires great care and constant vigilance. [1][2] Examples of risk factors include high voltages, high and low pressures and temperatures, corrosive and toxic chemicals and chemical vapours, radiation, fire, explosions, and biohazards ...
Common quantum logic gates by name (including abbreviation), circuit form(s) and the corresponding unitary matrices. In quantum computing and specifically the quantum circuit model of computation, a quantum logic gate (or simply quantum gate) is a basic quantum circuit operating on a small number of qubits.
