Abstract From the Canadian patent

A first mixture is prepared that contains labeled chain fragments which each has a common end adjacent to a primary nucleotide and a termination at a position from the primary through an nth nucleotide the, first mixture containing nucleotide chain fragments of each length from termination at the primary through termination of the nth nucleotide. A second mixture is prepared that contains labeled chain fragments beginning at the common end and terminating at positions from the first through the nth nucleotide, the second mixture containing chain fragments of each length terminating wherever either a first or a second of the four nucleotides occurs. A third mixture is prepared that contains …
