Dideoxy sequencing, also known as the chain terminating method or Sanger sequencing, is a DNA sequencing method created by Biochemist Fred Sanger and is used in determining the sequence of nucleotides in DNA[1].The basis of this method is down to the incorporation of the molecule 2',3'-dideoxynucleoside triphosphate (ddNTP). This molecule lacks a hydroxyl group so DNA polymerase can no longer form a phosphodiester bond[2]. This stops DNA replication.
