A gene is a discrete sequence of DNA nucleotides
Fred Sanger, late 1940's.
The sequencing method developed by Fred Sanger forms the basis of automated "cycle" sequencing reactions today. Fluorescent dyes are added to the reactions, and a laser within an automated DNA sequencing machine is used to analyze the DNA fragments produc

Two sequencing techniques were developed independently in the 1970s. The method developed by Fred Sanger used chemically altered "dideoxy" bases to terminate newly synthesized DNA fragments at specific bases (either A, C, T, or G). These fragments are th
