Techniques to read the sequence of DNA, letter by letter, have been available since the 1970s. However, the massive task of sequencing the three billion basepairs of the human genome required machines that could read and interpret the data.

Craig Venter, the leader of the private genome effort, talks about the "whole genome shotgun" technique that was used by Celera Genomics to sequence the human genome.
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
Professor Allen Moore explains that since the beginning of the human genome project sequencing technology has become considerably cheaper and we now have sequences for many different organisms.
