Researchers from the Royal Institute of Technology from Stockholm developed a type of this technique detecting the release of the anion pyrophosphate. The SOLiD and ion torrent types of this technique are grouped together as the "next-generation" methods, which supplanted an older version of this technique using phosphorus-32-labelled ATP, developed by Maxam and Gilbert. Multiple overlapping reads are combined into contigs in a (*) piecemeal type of this process. Chain-terminating dideoxynucleotides, or ddNTPs, are selectively incorporated in a type of this process named for a British biochemist. For 10 points, name these techniques, such as the "shotgun" and "Sanger" types, that determine the order of nucleotides in a molecule of DNA.
