1. An automated DNA sequencing apparatus comprising:

  • a reactor comprising reagents which provide at least two series of DNA products formed from a single primer and a DNA strand, each said DNA product of a said series differing in molecular weight and having a chain terminating agent at one end,separating means for separating said DNA products along one axis of the separator to form a series of bands, the intensity of substantially all nearby bands in a series being approximately the same, and the intensity of substantially all nearby bands in any one series being different from those of other series,band reading means for determining the position and intensity of each said band after said separating along said axis, andcomputing means that determines the DNA sequence of said DNA strand solely from said position and intensity of said bands along said axis and not from the wavelength of emission of light from any label that may be present in the separating means.
