DNA Sequencing - DNA sequencing has come a long way since the laborious and time-consuming methods of the 1970s. Now automated techniques allow for sequencing much faster and efficiently. The fastest method for high volume sequencing uses fluorescent dyes to label the four base pairs each of which emits at a different wavelength when illuminated by a laser. By chemically terminating the DNA strand systematically along its length (with a resolution of a single base pair) and tagging the end of each fragment length with a fluorescent label, the chain-terminating base nucleotides can be identified using an excitation source in a high-throughput automated sequencing process.
