The role of the ddNTPs is to stop replication because the next nucleotide in the growing strand cannot bind to them. It is for that reason that ddNTPs are fundamental in Sanger sequencing.
<h3>Sanger sequencing</h3>
Sanger sequencing is a technique used to sequence and thus determine the nucleotide order of a DNA chain.
This methodology (Sanger sequencing) was designed by Frederick Sanger in 1977.
In Sanger sequencing, the ddNTPs are used to stop the synthesis of a DNA strand due to the lack of a free hydroxyl group (OH) which is required for the replication of DNA.
