 1977 - Walter Gilbert & Frederick Sanger
But inability to easily read off the precise nucleotide sequences of DNA forestalled further advances in molecular genetics and all prospects of genetic engineering.
Walter Gilbert (with graduate student Allan M. Maxam) and Frederick Sanger, in 1977, working separately in the United States and England, developed new techniques for rapid DNA sequencing.
Sanger and Gilbert each took advantage of recently discovered enzymes and both methods benefited from improvements in gel electrophoresis, a method used for imaging the order of nucleotides.

 DNA sequencing - Wikipedia, the free encyclopedia
Similarly, research into pathogens may lead to treatments for contagious diseases.
In 1976-7, Allan Maxam and Walter Gilbert developed a method of DNA sequencing based on chemical modification of DNA followed by its subsequent cleavage [2].
This method supplemented earlier RNA sequencing approaches and was initially popular since purified DNA could be used directly, while alternative methods (below) required that each DNA to be read be cloned first production of single-stranded DNA.

He labeled the segments with radionucleotides, cut them with restriction enzymes, which break DNA at known locations, and separated the fragments by electrophoresis.
Gilbert and Allan Maxam developed a similar method for the other two DNA bases, thymine and cytosine, using the chemical hydrazine.
After identifying the base sequences in the fragments, Gilbert was able to reconstruct entire DNA strand sequences thus "reading the letters" in which genetic instructions were coded.

 BookRags: Walter Gilbert Biography
Working with graduate student Allan Maxam, he began to sequence parts of the DNA strand.
It was known that the molecules could be "broken" at specific chemical junctures by using certain chemical substances, and a colleague introduced Gilbert and Maxam to a procedure that broke DNA molecules into fragments that were easier to describe.
They used a technique known as gel electrophoresis, in which an electric current causes the fragments to pass through a gel substance.

Therefore, the development of a simple, inexpensive and sensitive direct detection system which eliminates the use of labels is highly desirable.
There are two main classical methods for sequencing DNA: The first method, developed by Allan Maxam and Walter Gilbert, involves chemicals used to cleave the DNA at certain positions, generating a set of fragments that differ by one nucleotide.
The second method, developed by Fred Sanger and Alan Coulson, involves enzymatic synthesis of DNA strands that terminate in a modified nucleotide.

The answer, quite naturally, lies somewhere in between.
In synthesizing the gene that makes hemoglobin in rabbits, Thomas Maniatis, assistant professor of Biochemistry and Molecular Biology; Fotis Kafatos, professor of Biology; Argiris Efstraiadis, doctor candidate in Biology; and Allan Maxam, research assistant in Biochemistry and Molecular Biology have carried science closer to being able to understand how genes express themselves in higher organisms.
On the other hand, the research by the Harvard team basically adds to reseaach done by a number of other teams at the National Institute of Health and several universities.
