Sanger sequencing reaction mixtures included purified template DNA, a primer, DNA polymerase, and all four dNTPs. Each reaction also included a radiolabeled ddNTP version of just one of the four nucleotides. Only a small amount of each ddNTP was added, however, to ensure that a fraction of the total DNA fragments produced stopped at each occurrence of that base. As with previous methods, separating fragments via length and performing autoradiography allowed scientists to read the final sequence.
this breaks things that should obviously work. take the distributive law: (a|ab)(c|b) and (a|ab)c|(a|ab)b are logically the same pattern - you can verify this yourself by just expanding the terms. but in PCRE, the first matches ab in the input abc, while the second matches abc. two equivalent patterns, two different results.
