Sanger Sequencing 2026

Sanger Sequencing is a DNA sequencing method that is best used for short - medium length sequences. Sanger Sequencing needs a DNA template(the DNA being studied), primers, polymerase, dNTP, and ddNTP. dNTP are the molecules used by DNA polymerase normally. dNTP molecules have a free 3'OH which is very crucial for elongation as it is needed for the formation of phosphodiester bonds. ddNTP are molecules that lacks the free 3'OH which terminates elongation of strands because DNA polymerase cannot add and connect the next nucleotide without that free 3'OH for phosphodiester bonds. Sanger sequencing basically uses ddNTP to randomly terminate sequences into fragments while also making sure that we specifically know what base was used for the ddNTP. Gel electrophoresis is partnered with this technique since we can use to read the fragments that were made from each test tube We read the bands in the gel from bottom to top since smaller fragments travel the fastest compared to bigger fragments. We can start inferring the sequence by basing off each band in the gels or making overlaps. To specifically obtain the sequence of the DNA template(or DNA that eas originally being studied), we need to do the complementary base pairing of the assembled sequences from the fragments.
