Sign in to report inappropriate content. Technical variations of chain-termination sequencing include tagging with nucleotides containing radioactive phosphorus for radiolabellingor using a primer labeled at the 5' end with a fluorescent dye.

    These chain-terminating nucleotides lack a 3'- OH group required for the formation of a phosphodiester bond between two nucleotides, causing DNA polymerase to cease extension of DNA when a modified ddNTP is incorporated.

    Add to Want to watch this again later? In dye-terminator sequencing, each of the four dideoxynucleotide chain terminators is labelled with fluorescent dyes, each of which emit light at different wavelengths. Dye-primer sequencing facilitates reading in an optical system for faster and more economical analysis and automation. Batch runs may occur up to 24 times a day. The longer read lengths in Sanger methods display significant advantages over other sequencing methods especially in terms of sequencing repetitive regions of the genome.

    Its limitations include dye effects due to differences in the incorporation of the dye-labelled chain terminators into the DNA fragment, resulting in unequal peak heights and shapes in the electronic DNA sequence trace chromatogram after capillary electrophoresis see figure to the left.

    The ultimate goal of high-throughput sequencing is to develop systems that are low-cost, and extremely efficient at obtaining extended longer read lengths.
