(A) Schematic of cyclic-array sequencing-by-synthesis methods (for example, fluorescent in situ sequencing, pyrosequencing, or single-molecule methods). Left: repeated cycles of polymerase extension ...

DNA sequencing refers to the process of identifying the order of bases in a strand of DNA. DNA is comprised of nucleotides, with each nucleotide consisting of a sugar, a phosphate group and a base.

Genomic sequencing opens the door to incredible amounts of data—data that changes the way we think about both research and clinical care. Unlike genotyping, which detects a person’s particular genetic ...
