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 ...
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.
Standard flowgram format (SFF) is a binary file format used to encode results of pyrosequencing from the 454 Life Sciences platform for high-throughput sequencing.SFF files can be viewed, edited and converted with DNA Baser SFF Workbench (graphic tool), or converted to FASTQ format with sff2fastq or seq_crumbs.
Example Bjerrum plot: Change in carbonate system of seawater from ocean acidification.. A Bjerrum plot (named after Niels Bjerrum), sometimes also known as a Sillén diagram (after Lars Gunnar Sillén), or a Hägg diagram (after Gunnar Hägg) [1] is a graph of the concentrations of the different species of a polyprotic acid in a solution, as a function of pH, [2] when the solution is at ...

In a de Bruijn graph, there is a possibility of 4^k different nodes to make arrangements of a genome. The number of nodes used to create the graph can be reduced in number by considering only the k-mers found within the DNA strand of interest. Given sequence 1, it is possible to determine the nodes of size 7, or 7-mers, that will be in the graph.
After reading the introduction I feel that the 454 should only be mentioned later under recent advantages. This way it appears that 454 is the only way pyrosequencing is applied. In addition, it is a bit of a repetition.CharonZ 10:06, 10 July 2007 (UTC)
Pyrosequencing has also been used to analyze bisulfite-treated DNA without using methylation-specific PCR. [7] [8] Following PCR amplification of the region of interest, pyrosequencing is used to determine the bisulfite-converted sequence of specific CpG sites in the region. The ratio of C-to-T at individual sites can be determined ...
