Also question is, how is Sanger sequencing different from PCR?
Sanger sequencing differs from PCR in that only a single primer is used in the reaction. Typically, for a given PCR fragment, two Sanger sequencing reactions are set up, one for sequencing the forward strand, the other one for sequencing the reverse strand. Primer length should be in the range of 18 to 22 bases.
Secondly, how does automated sequencing that uses Sanger principles differ from traditional Sanger sequencing? Automated sequencing has been developed to sequence a really large amount of DNA. This procedure uses the principle of the Sanger chain-termination method. Instead of labeling dATP in the original Sanger method, each of the dideoxynucleotides used in the reaction is labeled with a different fluorescent marker.
In this way, what is the Sanger sequencing method used for?
Sanger sequencing, also known as the “chain termination method”, is a method for determining the nucleotide sequence of DNA. The method was developed by two time Nobel Laureate Frederick Sanger and his colleagues in 1977, hence the name the Sanger Sequence. To review the general structure of DNA, please see Figure 2.
Is Sanger sequencing still used?
Sanger sequencing is still used in the labs today – and not only on the side. Next-generation sequencing has its strength when it comes to sequencing very large amounts of DNA (basically whole genomes or exomes). Sanger sequencing is used when you want to sequence smaller regions or portions of a genome/plasmid.

Sanger methods can only sequence short pieces of DNA–about 300 to 1000 base pairs. The quality of a Sanger sequence is often not very good in the first 15 to 40 bases because that is where the primer binds. Sequence quality degrades after 700 to 900 bases.

The Sanger Method is used to amplify a target segment of DNA, so that the DNA sequence can be determined precisely. The incorporation of ddNTPs in the reaction valves are simply used to terminate the synthesis of a growing DNA strand, resulting in partially replicated DNA fragments.
