DNA SEQUENCING

摘要

A method for sequencing a strand of DNA, including the steps of: providing the strand of DNA; annealing the strand with a primer able to hybridize to the strand to give an annealed mixture; incubating the mixture with a deoxyribonucleoside triphosphate, a DNA polymerase, and a chain terminating agent under conditions in which the polymerase causes the primer to be elongated to form a series of DNA products differing in length of the elongated primer, each DNA product having a chain terminating agent at its elongated end; the number of each DNA product being approximately the same for substantially all DNA products differing in length from 1 to 20 bases.
