Pyrosequencing is a method of DNA sequencing (determining the order of nucleotides in DNA) based on the "sequencing by synthesis" principle, in which the sequencing is performed by detecting the nucleotide incorporated by a DNA polymerase. Pyrosequencing relies on light detection based on a chain reaction when pyrophosphate is released. Hence ...
The pyrosequencing method is based on the detection of the pyrophosphate release on nucleotide incorporation. Before performing pyrosequencing, the DNA strand to sequence has to be amplified by PCR. Then the order in which the nucleotides have to be added in the sequencer is chosen (i.e. G-A-T-C).
Pyrosequencing uses luciferase to generate light for detection of the individual nucleotides added to the nascent DNA, and the combined data are used to generate sequence reads. [81] This technology provides intermediate read length and price per base compared to Sanger sequencing on one end and Solexa and SOLiD on the other.
The principle of Pyrosequencing was first described in 1993 [1] by combining a solid support with an engineered DNA polymerase lacking 3´to 5´exonuclease activity (proof-reading) and luminescence real-time detection using the firefly luciferase. All the key concepts of sequencing by synthesis were introduced, including (1) amplification of ...
Artificial gene synthesis, or simply gene synthesis, refers to a group of methods that are used in synthetic biology to construct and assemble genes from nucleotides de novo. Unlike DNA synthesis in living cells, artificial gene synthesis does not require template DNA, allowing virtually any DNA sequence to be synthesized in the laboratory.

Broader application benefited from pairwise end sequencing, known colloquially as double-barrel shotgun sequencing.As sequencing projects began to take on longer and more complicated DNA sequences, multiple groups began to realize that useful information could be obtained by sequencing both ends of a fragment of DNA.
