The objective for sequential sequencing by synthesis (SBS) is to determine the sequencing of a DNA sample by detecting the incorporation of a nucleotide by a DNA polymerase. An engineered polymerase is used to synthesize a copy of a single strand of DNA and the incorporation of each nucleotide is monitored.

Sanger sequencing requires two reactions, one for the forward primer and another for the reverse primer. Unlike Illumina, Sanger sequencing uses fluorescently labeled dideoxynucleoside triphosphates (ddNTPs) to determine the sequence of the DNA fragment. ddNTPs are missing the 3' OH group and terminates DNA synthesis permanently.

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 ...
This sequencing method is based on sequencing by synthesis (SBS) principle and the use of reversible dye-terminator that enables the identification of each single nucleotid. In order to read the transcript sequences on one end, and the barcode and UMI on the other end, paired-end sequencing readers are required.
The DNA sequencing is done on a chip that contains many ZMWs. Inside each ZMW, a single active DNA polymerase with a single molecule of single stranded DNA template is immobilized to the bottom through which light can penetrate and create a visualization chamber that allows monitoring of the activity of the DNA polymerase at a single molecule level.
So far, most DNA sequencing has been performed using the chain termination method developed by Frederick Sanger. This technique uses sequence-specific termination of a DNA synthesis reaction using modified nucleotide substrates. However, new sequencing technologies such as pyrosequencing are gaining an increasing share of the sequencing market ...
Degradome sequencing (Degradome-Seq), [1] [2] also referred to as parallel analysis of RNA ends (PARE), is a modified version of 5'-Rapid Amplification of cDNA Ends (RACE) using high-throughput, deep sequencing methods such as Illumina's SBS technology.
