Determination of DNA Sequence Information. Almost all DNA sequence is determined by enzymatic methods (12) which exploit the properties of the enzyme DNA polymerase. Whereas a chemical method for DNA sequencing exists, its use has been supplanted for the most part in the initial determination of a sequence. Chemical or Maxam-Gilbert sequencing (13) is more often used for mapping functional sites on DNA fragments of known sequence. 

In principle, the Maxam-Gilbert method can provide the total sequence of a dsDNA molecule just by determining the purine positions on one strand and then the purines on the complementary strand. Complementary base-pairing rules then reveal the pyrimidines along each strand, T complementary to where A is, C complementary to where G occurs. (The analogous approach of locating the pyrimidines on each strand would also provide sufficient information to write the total sequence.)... 

The Maxam-Gilbert method doesn t require synthesis of a primer and it sometimes works well for sequences that are difficult to obtain with the Sanger -Coulson procedure. The two methods may both be used to provide additional certainty about a sequence. The Maxam-Gilbert method is very convenient for sequencing small oligonucleotides which often react poorly with the polymerase used for the chain termination method. The method usually requires that a restriction map be prepared.

Since its introduction in 1977 this has become the most widely used sequencing procedure for DNA. In the intervening period the method has been refined and developed to the point where it has become the method of choice in laboratories all over the world. Though not as fast as the primed synthesis methods, it is, up to the time of writing the most widely tried and tested procedure and the majority of DNA sequences reported in the literature to date have been determined by the Maxam-Gilbert procedure.
