Sequencing DNA. Goal – obtain the string of bases that make a given DNA strand. Problem –Typically one cans sequence directly only DNA of short length (400-700 bp – Sanger; <200 - Illumina). Sequence assembly – the process of putting together the fragments.

• Sequencing by synthesis (“SBS”) – uses DNA polymerase in a primer extension reaction – most common approach – Sanger developed it (“Sanger sequencing”) – Illumina, Pacific Biosciences, Ion Torrent, 454 • Ligation-based – sequencing using short probes that hybridize to the template – SOLiD, Complete Genomics • Nanopore
This chapter aims to give an overview of the methodologies used to interrogate the human genome focusing mainly on genomic sequencing from Sanger sequencing to single-molecule DNA...
DNA sequencing methods were first developed more than 20 ago with the publication of two approaches to sequencing ology that became known as Sanger sequencing (1), based on matic synthesis from a single-stranded DNA template with termination using dideoxynucleotides (ddNTPs) and Maxim-Gilbert sequencing (2), which involved chemical degradation o...
2 maj 2023 · DNA sequencing is the process of determining the nucleotides in DNA. It includes any technology that is used to determine the order of the bases (DNTPs): adenine, guanine, cytosine, and thymine.
Below, we review early efforts to sequence biopolymers, the invention of electro-phoretic methods for DNA sequencing and their scaling to the Human Genome Project, and the emergence of second (massively parallel) and third (real-time, single-molecule) generation DNA sequencing. Some key technical milestones are also summarized in Box 1.
