Sanger method

DNA sequencing
Also known as: dideoxy method

Quick Summary

The Sanger method is a technique used to determine the nucleotide sequence of DNA. Developed by Frederick Sanger, this method involves synthesizing DNA chains on a template. Chain growth is halted when a special dideoxy nucleotide is incorporated, preventing further addition. This process creates a set of truncated DNA molecules, each representing a specific position of a nucleotide in the original DNA. These fragments are then separated by electrophoresis, and a computer analyzes the results to deduce the DNA sequence. This method was a foundational "first-generation" sequencing technology, largely superseded by faster and more cost-efficient "next-generation" approaches.123
