How does the Illumina sequencer read DNA?
How does the Illumina sequencer read DNA?
Illumina next-generation sequencing (NGS) technology uses clonal amplification and sequencing by synthesis (SBS) chemistry to enable rapid, accurate sequencing. The process simultaneously identifies DNA bases while incorporating them into a nucleic acid chain.
What is automated DNA sequencing?
Automated DNA sequencing utilizes a fluorescent dye to label the nucleotides instead of a radioactive isotope. The system automatically identifies the nucleotide sequence and saves the information on the computer. Thus, only a review of the data is necessary to ensure no anomalies were misidentified by the computer.
What is Illumina short read sequencing?
Illumina sequencing by synthesis technology supports both single-read and paired-end libraries. SBS technology offers a short-insert paired-end capability for high-resolution genome sequencing, as well as long-insert paired-end reads for efficient sequence assembly, de novo sequencing, and more.
Does Illumina use DNA polymerase?
With Sanger sequencing, only one strand is able to be sequenced at a time and is relatively slow. Illumina only uses DNA polymerase as opposed to multiple, expensive enzymes required by other sequencing techniques (i.e. pyrosequencing).

What is Illumina sequencing?
Illumina sequencing utilizes a fundamentally different approach from the classic Sanger chain-termination method. It leverages sequencing by synthesis (SBS) technology – tracking the addition of labeled nucleotides as the DNA chain is copied – in a massively parallel fashion.
What is the latest technology in Illumina NGS?
Evolution of Illumina NGS. Recent Illumina next-generation sequencing technology breakthroughs include: Semiconductor sequencing with CMOS technology: The iSeq 100 System combines a complementary metal-oxide semiconductor (CMOS) chip with one-channel SBS to deliver high-accuracy data in a compact system.
What is DNA sequencing?
Sequencing of the fragments through cycles of biochemical reactions. During the reaction cycles, information is acquired which allows, by specific software, to reconstruct a DNA or cDNA sequence. This phase also varies according to the technique used.
What is a single index illumina adapter?
Single index Illumina adapters. These adapters contain a barcode (or index), that is the DNA sequences that identify a specific sample (where sample means a specific genotype) therefore by inserting these sequences inside the adapters it is possible to sequence the fragments related to different genotypes simultaneously.
